| CVE-2026-58380 | 3 Gimp, Gnome, Redhat | 3 Gimp, Gimp, Enterprise Linux | 2026-09-02 | 7.3 High |
| A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution. | ||||
| CVE-2026-66758 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-09-02 | 7.8 High |
| A flaw was found in the file-fits plugin in GIMP. When processing a FITS image file, the plugin calculates memory allocation sizes using signed 32-bit integers for width and height. If a crafted file sets both values to large values, their product exceeds 2^31 and overflows, resulting in an undersized heap-based buffer allocation. This integer overflow issue results in a heap-based buffer overflow when cfitsio subsequently writes a full row of pixels in the buffer, causing memory corruption, potentially leading to arbitrary code execution or a denial of service. | ||||
| CVE-2026-84268 | 1 Redhat | 1 Enterprise Linux | 2026-09-02 | 8.8 High |
| A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious SFTP server can cause read_reply() to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the allocated buffer size, causing the operation to write past the intended boundaries. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution. | ||||
| CVE-2026-72693 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-09-02 | 7.8 High |
| `openvt -u` is intended to identify the owner of the current VT and then execute `login` as that user from a privileged context. In the documented `kbrequest`/init usage, the ownership test in `authenticate_user()` relies on `stat("/proc/<pid>/fd/0")`. `stat()` on `/proc/<pid>/fd/0` follows the symlink to the underlying TTY device node. As a result, `buf.st_uid` reflects the owner of the TTY node rather than the owner of the process holding the file descriptor. If the TTY owner returns to `root` or the getty owner after logout while an unprivileged process still has `fd 0` attached to that TTY, the check can incorrectly treat that process as belonging to the privileged console owner. Once that check succeeds, the `-u` path executes a passwordless login as the selected user. In the documented `kbrequest`/init deployment using `openvt -us`, this can result in passwordless `login -f root` on the spawned VT. This report establishes that privilege escalation path for that documented deployment; it does not claim equivalent reachability for deployments that do not use `openvt -u` from a privileged `kbrequest`/init path. | ||||
| CVE-2026-59850 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | 4.3 Medium |
| A flaw was found in libssh. If data packets are processed after a channel is closed, channel data callbacks can be invoked after the associated data has already been freed, leading to crashes or possible use-after-free conditions. | ||||
| CVE-2026-59848 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | 5.3 Medium |
| A flaw was found in libssh. A malicious SFTP server can send responses for unknown request IDs that libssh clients keep queued indefinitely, causing unbounded memory growth and client-side denial of service. | ||||
| CVE-2026-59846 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | 3.9 Low |
| A flaw was found in libssh. A malicious username expanded through %r in ProxyCommand handling can inject shell metacharacters, exposing environment variables and causing unintended shell behavior. | ||||
| CVE-2026-59845 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | 5.3 Medium |
| A flaw was found in libssh. When ProxyCommand is used, an unchecked fork() failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service. | ||||
| CVE-2026-59844 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | 6.5 Medium |
| A flaw was found in libssh. A remote authenticated client can issue SSH_FXP_READ requests with an arbitrarily large length, causing a libssh SFTP server to allocate excessive memory and potentially exhaust it through repeated requests. | ||||
| CVE-2026-59843 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | 6.5 Medium |
| A flaw was found in libssh. A remote authenticated peer can advertise a zero maximum packet size in SSH_MSG_CHANNEL_OPEN, causing later channel writes to loop indefinitely and consume CPU, leading to denial of service. | ||||
| CVE-2026-84270 | 1 Redhat | 1 Enterprise Linux | 2026-09-01 | 4.3 Medium |
| A flaw was found in the MTP backend in gvfs. When reading a file from a mounted MTP device, do_read() in gvfsbackendmtp.c trusts the data length returned by the device without limiting it to the original size requested by the client. If a malicious MTP device responds with more bytes than requested, this unrestricted length is passed directly to memcpy(). This causes the operation to read memory outside the intended boundaries. This allows an attacker who plugs in a malicious MTP device to cause a segmentation fault when a file is read and crash the gvfsd-mtp process, resulting in a denial of service. | ||||
| CVE-2026-81624 | 1 Redhat | 9 Build Of Apache Camel For Spring Boot, Camel Spring Boot, Enterprise Linux and 6 more | 2026-09-01 | 7.5 High |
| Undertow is a flexible performant web server used in JBoss EAP and WildFly. A flaw was found in how Undertow handles WebSocket connections. Specifically, certain configuration limits like message buffer sizes and session timeouts cannot be adjusted and default to being unlimited. This allows a remote attacker to send large amounts of data or maintain connections indefinitely, potentially crashing the server by exhausting its memory or other resources. | ||||
| CVE-2026-84267 | 1 Redhat | 1 Enterprise Linux | 2026-09-01 | 4.3 Medium |
| A flaw was found in the SFTP backend in gvfs. When mounting a share, a malicious SFTP server can cause read_string() to allocate a buffer with a certain length but the function does not verify that the buffer is completely filled, leaving the remainder of the buffer containing uninitialized heap contents. If the server sends a short FXP_HANDLE reply, these uninitialized bytes are taken as the file handle. The client will then echo these uninitialized bytes back to the server on all subsequent requests using that handle. With a length of 128 bytes, this issue allows the malicious server to deterministically read uninitialized heap memory from the gvfsd-sftp process, leaking its heap base and the load address of the libgio library, resulting in a deterministic defeat of Address Space Layout Randomization (ASLR). | ||||
| CVE-2020-8619 | 7 Canonical, Debian, Fedoraproject and 4 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2026-09-01 | 4.9 Medium |
| In ISC BIND9 versions BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk ("*") character, this defect cannot be encountered. A would-be attacker who is allowed to change zone content could theoretically introduce such a record in order to exploit this condition to cause denial of service, though we consider the use of this vector unlikely because any such attack would require a significant privilege level and be easily traceable. | ||||
| CVE-2022-38177 | 5 Debian, Fedoraproject, Isc and 2 more | 8 Debian Linux, Fedora, Bind and 5 more | 2026-09-01 | 7.5 High |
| By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. | ||||
| CVE-2022-2795 | 4 Debian, Fedoraproject, Isc and 1 more | 5 Debian Linux, Fedora, Bind and 2 more | 2026-09-01 | 5.3 Medium |
| By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service. | ||||
| CVE-2018-5745 | 2 Isc, Redhat | 2 Bind, Enterprise Linux | 2026-09-01 | 4.9 Medium |
| "managed-keys" is a feature which allows a BIND resolver to automatically maintain the keys used by trust anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys feature it is possible for a BIND server which uses managed-keys to exit due to an assertion failure if, during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P1, 9.12.0 -> 9.12.3-P1, and versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2018-5745. | ||||
| CVE-2022-38178 | 5 Debian, Fedoraproject, Isc and 2 more | 8 Debian Linux, Fedora, Bind and 5 more | 2026-09-01 | 7.5 High |
| By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. | ||||
| CVE-2024-11831 | 1 Redhat | 34 Acm, Advanced Cluster Security, Ansible Automation Platform and 31 more | 2026-09-01 | 5.4 Medium |
| A flaw was found in npm-serialize-javascript. The vulnerability occurs because the serialize-javascript module does not properly sanitize certain inputs, such as regex or other JavaScript object types, allowing an attacker to inject malicious code. This code could be executed when deserialized by a web browser, causing Cross-site scripting (XSS) attacks. This issue is critical in environments where serialized data is sent to web clients, potentially compromising the security of the website or web application using this package. | ||||
| CVE-2026-16615 | 2 Gnome, Redhat | 3 Librest, Enterprise Linux, Enterprise Linux Eus | 2026-09-01 | 6.8 Medium |
| A flaw was found in librest. The PKCE implementation for OAuth authorization uses the GRand function from the GLib API, a cryptographically insecure pseudo-random number generator. Because the generated "code verifier" lacks sufficient cryptographic entropy, a malicious actor can reverse-engineer the pseudo-random number generator (PRNG) seed to predict or reconstruct the code verifier string, allowing an attacker to bypass PKCE protections and successfully impersonate the client during the OAuth 2.0 authorization flow. | ||||
