| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2017-5753 | 14 Arm, Canonical, Debian and 11 more | 396 Cortex-a12, Cortex-a12 Firmware, Cortex-a15 and 393 more | 2026-05-28 | 5.6 Medium |
| Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. | ||||
| CVE-2015-2808 | 9 Canonical, Debian, Fujitsu and 6 more | 102 Ubuntu Linux, Debian Linux, Sparc Enterprise M3000 and 99 more | 2026-05-28 | 3.7 Low |
| The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic that occasionally relies on keys affected by the Invariance Weakness, and then using a brute-force approach involving LSB values, aka the "Bar Mitzvah" issue. | ||||
| CVE-2015-4000 | 13 Apple, Canonical, Debian and 10 more | 31 Iphone Os, Mac Os X, Safari and 28 more | 2026-05-27 | 3.7 Low |
| The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue. | ||||
| CVE-2009-3555 | 9 Apache, Canonical, Debian and 6 more | 15 Http Server, Ubuntu Linux, Debian Linux and 12 more | 2026-05-27 | 9.8 Critical |
| The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. | ||||
| CVE-2015-8325 | 4 Canonical, Debian, Openbsd and 1 more | 6 Ubuntu Core, Ubuntu Linux, Ubuntu Touch and 3 more | 2026-05-22 | 7.8 High |
| The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable. | ||||
| CVE-2013-2566 | 4 Canonical, Fujitsu, Mozilla and 1 more | 24 Ubuntu Linux, M10-1, M10-1 Firmware and 21 more | 2026-05-22 | 5.9 Medium |
| The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext. | ||||
| CVE-2023-4911 | 7 Canonical, Debian, Fedoraproject and 4 more | 51 Ubuntu Linux, Debian Linux, Fedora and 48 more | 2026-05-12 | 7.8 High |
| A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. | ||||
| CVE-2018-17958 | 4 Canonical, Debian, Qemu and 1 more | 8 Ubuntu Linux, Debian Linux, Qemu and 5 more | 2026-04-28 | 7.5 High |
| Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used. | ||||
| CVE-2016-10708 | 5 Canonical, Debian, Netapp and 2 more | 13 Ubuntu Linux, Debian Linux, Cloud Backup and 10 more | 2026-04-28 | 7.5 High |
| sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. | ||||
| CVE-2009-1888 | 4 Canonical, Debian, Redhat and 1 more | 5 Ubuntu Linux, Debian Linux, Enterprise Linux and 2 more | 2026-04-23 | N/A |
| The acl_group_override function in smbd/posix_acls.c in smbd in Samba 3.0.x before 3.0.35, 3.1.x and 3.2.x before 3.2.13, and 3.3.x before 3.3.6, when dos filemode is enabled, allows remote attackers to modify access control lists for files via vectors related to read access to uninitialized memory. | ||||
| CVE-2007-5268 | 2 Canonical, Libpng | 2 Ubuntu Linux, Libpng | 2026-04-23 | N/A |
| pngrtran.c in libpng before 1.0.29 and 1.2.x before 1.2.21 use (1) logical instead of bitwise operations and (2) incorrect comparisons, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG image. | ||||
| CVE-2008-4989 | 7 Canonical, Debian, Fedoraproject and 4 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2026-04-23 | 5.9 Medium |
| The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN). | ||||
| CVE-2007-6420 | 2 Apache, Canonical | 2 Http Server, Ubuntu Linux | 2026-04-23 | N/A |
| Cross-site request forgery (CSRF) vulnerability in the balancer-manager in mod_proxy_balancer for Apache HTTP Server 2.2.x allows remote attackers to gain privileges via unspecified vectors. | ||||
| CVE-2009-0322 | 4 Canonical, Debian, Linux and 1 more | 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more | 2026-04-23 | N/A |
| drivers/firmware/dell_rbu.c in the Linux kernel before 2.6.27.13, and 2.6.28.x before 2.6.28.2, allows local users to cause a denial of service (system crash) via a read system call that specifies zero bytes from the (1) image_type or (2) packet_size file in /sys/devices/platform/dell_rbu/. | ||||
| CVE-2006-6143 | 2 Canonical, Mit | 2 Ubuntu Linux, Kerberos 5 | 2026-04-23 | N/A |
| The RPC library in Kerberos 5 1.4 through 1.4.4, and 1.5 through 1.5.1, as used in Kerberos administration daemon (kadmind) and other products that use this library, calls an uninitialized function pointer in freed memory, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors. | ||||
| CVE-2008-5017 | 4 Canonical, Debian, Mozilla and 1 more | 6 Ubuntu Linux, Debian Linux, Firefox and 3 more | 2026-04-23 | N/A |

| CVE-2008-5019 | 4 Canonical, Debian, Mozilla and 1 more | 4 Ubuntu Linux, Debian Linux, Firefox and 1 more | 2026-04-23 | N/A |
| The session restore feature in Mozilla Firefox 3.x before 3.0.4 and 2.x before 2.0.0.18 allows remote attackers to violate the same origin policy to conduct cross-site scripting (XSS) attacks and execute arbitrary JavaScript with chrome privileges via unknown vectors. | ||||
| CVE-2007-0908 | 3 Canonical, Php, Redhat | 5 Ubuntu Linux, Php, Enterprise Linux and 2 more | 2026-04-23 | N/A |
| The WDDX deserializer in the wddx extension in PHP 5 before 5.2.1 and PHP 4 before 4.4.5 does not properly initialize the key_length variable for a numerical key, which allows context-dependent attackers to read stack memory via a wddxPacket element that contains a variable with a string name before a numerical variable. | ||||
| CVE-2006-5158 | 3 Canonical, Linux, Redhat | 7 Ubuntu Linux, Linux Kernel, Enterprise Linux and 4 more | 2026-04-23 | 7.5 High |
| The nlmclnt_mark_reclaim in clntlock.c in NFS lockd in Linux kernel before 2.6.16 allows remote attackers to cause a denial of service (process crash) and deny access to NFS exports via unspecified vectors that trigger a kernel oops (null dereference) and a deadlock. | ||||
