CVE-2016-1834 6 Apple, Canonical, Debian and 3 more 16 Iphone Os, Mac Os X, Tvos and 13 more 2025-12-04 7.8 High
Heap-based buffer overflow in the xmlStrncat function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.
CVE-2016-5131 8 Apple, Canonical, Debian and 5 more 18 Iphone Os, Mac Os X, Tvos and 15 more 2025-12-04 8.8 High
Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function.
CVE-2016-3627 7 Canonical, Debian, Hp and 4 more 15 Ubuntu Linux, Debian Linux, Icewall Federation Agent and 12 more 2025-12-04 7.5 High
The xmlStringGetNodeList function in tree.c in libxml2 2.9.3 and earlier, when used in recovery mode, allows context-dependent attackers to cause a denial of service (infinite recursion, stack consumption, and application crash) via a crafted XML document.
CVE-2025-7044 1 Canonical 1 Maas 2025-12-04 7.7 High
An Improper Input Validation vulnerability exists in the user websocket handler of MAAS. An authenticated, unprivileged attacker can intercept a user.update websocket request and inject the is_superuser property set to true. The server improperly validates this input, allowing the attacker to self-promote to an administrator role. This results in full administrative control over the MAAS deployment.
CVE-2016-9318 4 Canonical, Redhat, Xmlsec Project and 1 more 4 Ubuntu Linux, Jboss Core Services, Xmlsec and 1 more 2025-12-04 5.5 Medium
libxml2 2.9.4 and earlier, as used in XMLSec 1.2.23 and earlier and other products, does not offer a flag directly indicating that the current document may be read but other files may not be opened, which makes it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document.
CVE-2016-9842 8 Apple, Canonical, Debian and 5 more 22 Iphone Os, Mac Os X, Tvos and 19 more 2025-12-04 8.8 High
The inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving left shifts of negative integers.
CVE-2017-9022 3 Canonical, Debian, Strongswan 3 Ubuntu Linux, Debian Linux, Strongswan 2025-12-03 7.5 High
The gmp plugin in strongSwan before 5.5.3 does not properly validate RSA public keys before calling mpz_powm_sec, which allows remote peers to cause a denial of service (floating point exception and process crash) via a crafted certificate.
CVE-2017-6519 3 Avahi, Canonical, Redhat 3 Avahi, Ubuntu Linux, Enterprise Linux 2025-12-03 9.1 Critical
avahi-daemon in Avahi through 0.6.32 and 0.7 inadvertently responds to IPv6 unicast queries with source addresses that are not on-link, which allows remote attackers to cause a denial of service (traffic amplification) and may cause information leakage by obtaining potentially sensitive information from the responding device via port-5353 UDP packets. NOTE: this may overlap CVE-2015-2809.
CVE-2018-16152 3 Canonical, Debian, Strongswan 3 Ubuntu Linux, Debian Linux, Strongswan 2025-12-03 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 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 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Ansible Tower and 3 more 2025-12-03 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 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 7.8 High
Net-SNMP through 5.7.3 allows Escalation of Privileges because of UNIX symbolic link (symlink) following.
CVE-2019-19956 8 Canonical, Debian, Fedoraproject and 5 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2025-12-03 7.5 High
xmlParseBalancedChunkMemoryRecover in parser.c in libxml2 before 2.9.10 has a memory leak related to newDoc->oldNs.
CVE-2019-15166 8 Apple, Canonical, Debian and 5 more 10 Mac Os X, Ubuntu Linux, Debian Linux and 7 more 2025-12-03 1.6 Low
lmp_print_data_link_subobjs() in print-lmp.c in tcpdump before 4.9.3 lacks certain bounds checks.
CVE-2019-15165 8 Apple, Canonical, Debian and 5 more 12 Ipados, Iphone Os, Mac Os X and 9 more 2025-12-03 5.3 Medium
sf-pcapng.c in libpcap before 1.9.1 does not properly validate the PHB header length before allocating memory.
CVE-2020-7595 8 Canonical, Debian, Fedoraproject and 5 more 35 Ubuntu Linux, Debian Linux, Fedora and 32 more 2025-12-03 7.5 High
xmlStringLenDecodeEntities in parser.c in libxml2 2.9.10 has an infinite loop in a certain end-of-file situation.
CVE-2020-8597 5 Canonical, Debian, Point-to-point Protocol Project and 2 more 8 Ubuntu Linux, Debian Linux, Point-to-point Protocol and 5 more 2025-12-03 9.8 Critical
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-2025-2486 2 Canonical, Ubuntu 3 Ubuntu, Edk2, Ubuntu 2025-12-01 N/A
The Ubuntu edk2 UEFI firmware packages accidentally allowed the UEFI Shell to be accessed in Secure Boot environments, possibly allowing bypass of Secure Boot constraints. Versions 2024.05-2ubuntu0.3 and 2024.02-2ubuntu0.3 disable the Shell. Some previous versions inserted a secure-boot-based decision to continue running inside the Shell itself, which is believed to be sufficient to enforce Secure Boot restrictions. This is an additional repair on top of the incomplete fix for CVE-2023-48733.
CVE-2018-5168 4 Canonical, Debian, Mozilla and 1 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2025-11-25 N/A
Sites can bypass security checks on permissions to install lightweight themes by manipulating the "baseURI" property of the theme element. This could allow a malicious site to install a theme without user interaction which could contain offensive or embarrassing images. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
