CVE-2018-16152 3 Canonical, Debian, Strongswan 3 Ubuntu Linux, Debian Linux, Strongswan 2025-12-03 5.0 MEDIUM 7.5 HIGH
In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data in the digestAlgorithm.parameters field during PKCS#1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation when only an RSA signature is used for IKEv2 authentication. This is a variant of CVE-2006-4790 and CVE-2014-1568.
CVE-2018-16151 3 Canonical, Debian, Strongswan 3 Ubuntu Linux, Debian Linux, Strongswan 2025-12-03 5.0 MEDIUM 7.5 HIGH
In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data after the encoded algorithm OID during PKCS#1 v1.5 signature verification. Similar to the flaw in the same version of strongSwan regarding digestAlgorithm.parameters, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation when only an RSA signature is used for IKEv2 authentication.
CVE-2018-14404 3 Canonical, Debian, Xmlsoft 3 Ubuntu Linux, Debian Linux, Libxml2 2025-12-03 5.0 MEDIUM 6.5 MEDIUM
A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case. Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application.
CVE-2018-11574 2 Canonical, Point-to-point Protocol Project 2 Ubuntu Linux, Point-to-point Protocol 2025-12-03 7.5 HIGH 9.8 CRITICAL
Improper input validation together with an integer overflow in the EAP-TLS protocol implementation in PPPD may cause a crash, information disclosure, or authentication bypass. This implementation is distributed as a patch for PPPD 0.91, and includes the affected eap.c and eap-tls.c files. Configurations that use the `refuse-app` option are unaffected.
CVE-2020-15861 3 Canonical, Net-snmp, Netapp 5 Ubuntu Linux, Net-snmp, Cloud Backup and 2 more 2025-12-03 7.2 HIGH 7.8 HIGH

eap.c in pppd in ppp 2.4.2 through 2.4.8 has an rhostname buffer overflow in the eap_request and eap_response functions.
CVE-2020-7595 7 Canonical, Debian, Fedoraproject and 4 more 32 Ubuntu Linux, Debian Linux, Fedora and 29 more 2025-12-03 5.0 MEDIUM 7.5 HIGH
xmlStringLenDecodeEntities in parser.c in libxml2 2.9.10 has an infinite loop in a certain end-of-file situation.
CVE-2013-5613 6 Canonical, Fedoraproject, Mozilla and 3 more 16 Ubuntu Linux, Fedora, Firefox and 13 more 2025-11-25 10.0 HIGH 9.8 CRITICAL
Use-after-free vulnerability in the PresShell::DispatchSynthMouseMove function in Mozilla Firefox before 26.0, Firefox ESR 24.x before 24.2, Thunderbird before 24.2, and SeaMonkey before 2.23 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving synthetic mouse movement, related to the RestyleManager::GetHoverGeneration function.
CVE-2018-5148 4 Canonical, Debian, Mozilla and 1 more 7 Ubuntu Linux, Debian Linux, Firefox and 4 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur in the compositor during certain graphics operations when a raw pointer is used instead of a reference counted one. This results in a potentially exploitable crash. This vulnerability affects Firefox ESR < 52.7.3 and Firefox < 59.0.2.
CVE-2018-12386 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2025-11-25 5.8 MEDIUM 8.1 HIGH
A vulnerability in register allocation in JavaScript can lead to type confusion, allowing for an arbitrary read and write. This leads to remote code execution inside the sandboxed content process when triggered. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3.
CVE-2014-1486 7 Canonical, Debian, Fedoraproject and 4 more 16 Ubuntu Linux, Debian Linux, Fedora and 13 more 2025-11-25 10.0 HIGH 9.8 CRITICAL
Use-after-free vulnerability in the imgRequestProxy function in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 allows remote attackers to execute arbitrary code via vectors involving unspecified Content-Type values for image data.
