| CVE-2023-40546 | 2 Fedoraproject, Redhat | 7 Fedora, Enterprise Linux, Rhel Aus and 4 more | 2025-11-20 | 6.2 Medium |
| A flaw was found in Shim when an error happened while creating a new ESL variable. If Shim fails to create the new variable, it tries to print an error message to the user; however, the number of parameters used by the logging function doesn't match the format string used by it, leading to a crash under certain circumstances. | ||||
| CVE-2023-4001 | 3 Fedoraproject, Gnu, Redhat | 4 Fedora, Grub2, Enterprise Linux and 1 more | 2025-11-20 | 6.8 Medium |
| An authentication bypass flaw was found in GRUB due to the way that GRUB uses the UUID of a device to search for the configuration file that contains the password hash for the GRUB password protection feature. An attacker capable of attaching an external drive such as a USB stick containing a file system with a duplicate UUID (the same as in the "/boot/" file system) can bypass the GRUB password protection feature on UEFI systems, which enumerate removable drives before non-removable ones. This issue was introduced in a downstream patch in Red Hat's version of grub2 and does not affect the upstream package. | ||||
| CVE-2023-3961 | 3 Fedoraproject, Redhat, Samba | 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more | 2025-11-20 | 9.1 Critical |
| A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand. However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe name containing Unix directory traversal characters (../). This could result in SMB clients connecting as root to Unix domain sockets outside the private directory. If an attacker or client managed to send a pipe name resolving to an external service using an existing Unix domain socket, it could potentially lead to unauthorized access to the service and consequential adverse events, including compromise or service crashes. | ||||
| CVE-2023-42669 | 2 Redhat, Samba | 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 7 more | 2025-11-20 | 6.5 Medium |
| A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. The DoS affects all other services as "rpcecho" runs in the main RPC task. | ||||
| CVE-2023-4091 | 3 Fedoraproject, Redhat, Samba | 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more | 2025-11-20 | 6.5 Medium |
| A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions when the Samba VFS module "acl_xattr" is configured with "acl_xattr:ignore system acls = yes". The SMB protocol allows opening files when the client requests read-only access but then implicitly truncates the opened file to 0 bytes if the client specifies a separate OVERWRITE create disposition request. The issue arises in configurations that bypass kernel file system permissions checks, relying solely on Samba's permissions. | ||||
| CVE-2024-10041 | 2 Linux-pam, Redhat | 3 Linux-pam, Enterprise Linux, Rhel Eus | 2025-11-20 | 4.7 Medium |
| A vulnerability was found in PAM. The secret information is stored in memory, where the attacker can trigger the victim program to execute by sending characters to its standard input (stdin). As this occurs, the attacker can train the branch predictor to execute an ROP chain speculatively. This flaw could result in leaked passwords, such as those found in /etc/shadow while performing authentications. | ||||
| CVE-2024-0567 | 5 Debian, Fedoraproject, Gnu and 2 more | 9 Debian Linux, Fedora, Gnutls and 6 more | 2025-11-20 | 7.5 High |
| A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack. | ||||
| CVE-2023-7192 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2025-11-20 | 5.5 Medium |
| A memory leak problem was found in ctnetlink_create_conntrack in net/netfilter/nf_conntrack_netlink.c in the Linux Kernel. This issue may allow a local attacker with CAP_NET_ADMIN privileges to cause a denial of service (DoS) attack due to a refcount overflow. | ||||
| CVE-2023-4806 | 3 Fedoraproject, Gnu, Redhat | 24 Fedora, Glibc, Codeready Linux Builder Eus and 21 more | 2025-11-20 | 5.9 Medium |
| A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags. | ||||
| CVE-2023-34968 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux and 4 more | 2025-11-20 | 5.3 Medium |
| A path disclosure vulnerability was found in Samba. As part of the Spotlight protocol, Samba discloses the server-side absolute path of shares, files, and directories in the results for search queries. This flaw allows a malicious client or an attacker with a targeted RPC request to view the information that is part of the disclosed path. | ||||
| CVE-2023-34967 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux and 4 more | 2025-11-20 | 5.3 Medium |
| A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets, one encoded data structure is a key-value style dictionary where the keys are character strings, and the values can be any of the supported types in the mdssvc protocol. Due to a lack of type checking in callers of the dalloc_value_for_key() function, which returns the object associated with a key, a caller may trigger a crash in talloc_get_size() when talloc detects that the passed-in pointer is not a valid talloc pointer. With an RPC worker process shared among multiple client connections, a malicious client or attacker can trigger a process crash in a shared RPC mdssvc worker process, affecting all other clients this worker serves. | ||||
| CVE-2023-34966 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux and 4 more | 2025-11-20 | 7.5 High |
| An infinite loop vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not validate a field in the network packet that contains the count of elements in an array-like structure. By passing 0 as the count value, the attacked function will run in an endless loop consuming 100% CPU. This flaw allows an attacker to issue a malformed RPC request, triggering an infinite loop, resulting in a denial of service condition. | ||||
| CVE-2022-2127 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux and 4 more | 2025-11-20 | 5.9 Medium |
| An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan manager response length. When Winbind is used for NTLM authentication, a maliciously crafted request can trigger an out-of-bounds read in Winbind, possibly resulting in a crash. | ||||
| CVE-2023-40547 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2025-11-20 | 8.3 High |
| A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled values when parsing an HTTP response. This flaw allows an attacker to craft a specific malicious HTTP request, leading to a completely controlled out-of-bounds write primitive and complete system compromise. This flaw is only exploitable during the early boot phase, an attacker needs to perform a Man-in-the-Middle or compromise the boot server to be able to exploit this vulnerability successfully. | ||||
| CVE-2023-3899 | 2 Fedoraproject, Redhat | 24 Fedora, Enterprise Linux, Enterprise Linux Desktop and 21 more | 2025-11-20 | 7.8 High |
| A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary configuration directives for /etc/rhsm/rhsm.conf, which can be abused to cause a local privilege escalation to an unconfined root. | ||||
| CVE-2024-3183 | 1 Redhat | 9 Enterprise Linux, Enterprise Linux Aus, Enterprise Linux Eus and 6 more | 2025-11-20 | 8.1 High |
| A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the client’s session key. This key is different for each new session, which protects it from brute force attacks. However, the ticket it contains is encrypted using the target principal key directly. For user principals, this key is a hash of a public per-principal randomly-generated salt and the user’s password. If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any principal, all of them being encrypted by their own key directly. By taking these tickets and salts offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when combined to a principal salt (i.e. find the principal’s password). | ||||
| CVE-2024-2698 | 2 Freeipa, Redhat | 4 Freeipa, Enterprise Linux, Enterprise Linux Eus and 1 more | 2025-11-20 | 8.8 High |
| A vulnerability was found in FreeIPA in how the initial implementation of MS-SFU by MIT Kerberos was missing a condition for granting the "forwardable" flag on S4U2Self tickets. Fixing this mistake required adding a special case for the check_allowed_to_delegate() function: If the target service argument is NULL, then it means the KDC is probing for general constrained delegation rules and not checking a specific S4U2Proxy request. In FreeIPA 4.11.0, the behavior of ipadb_match_acl() was modified to match the changes from upstream MIT Kerberos 1.20. However, a mistake resulting in this mechanism applies in cases where the target service argument is set AND where it is unset. This results in S4U2Proxy requests being accepted regardless of whether or not there is a matching service delegation rule. | ||||
| CVE-2023-5557 | 2 Gnome, Redhat | 6 Tracker Miners, Enterprise Linux, Rhel Aus and 3 more | 2025-11-20 | 7.5 High |
| A flaw was found in the tracker-miners package. A weakness in the sandbox allows a maliciously-crafted file to execute code outside the sandbox if the tracker-extract process has first been compromised by a separate vulnerability. | ||||
| CVE-2023-6478 | 4 Debian, Redhat, Tigervnc and 1 more | 11 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 8 more | 2025-11-20 | 7.6 High |
| A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information. | ||||
| CVE-2025-2784 | 2 Gnome, Redhat | 26 Libsoup, Codeready Linux Builder, Codeready Linux Builder For Arm64 and 23 more | 2025-11-18 | 7 High |
| A flaw was found in libsoup. The package is vulnerable to a heap buffer over-read when sniffing content via the skip_insight_whitespace() function. Libsoup clients may read one byte out-of-bounds in response to a crafted HTTP response by an HTTP server. | ||||
