CVE-2021-45960 6 Debian, Libexpat Project, Netapp and 3 more 10 Debian Linux, Libexpat, Active Iq Unified Manager and 7 more 2025-05-05 8.8 High
In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
CVE-2017-11742 2 Libexpat Project, Microsoft 2 Libexpat, Windows 2025-04-20 N/A
The writeRandomBytes_RtlGenRandom function in xmlparse.c in libexpat in Expat 2.2.1 and 2.2.2 on Windows allows local users to gain privileges via a Trojan horse ADVAPI32.DLL in the current working directory because of an untrusted search path, aka DLL hijacking.
CVE-2015-1283 9 Canonical, Debian, Google and 6 more 14 Ubuntu Linux, Debian Linux, Chrome and 11 more 2025-04-12 N/A
Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716.
CVE-2016-5300 4 Canonical, Debian, Google and 1 more 4 Ubuntu Linux, Debian Linux, Android and 1 more 2025-04-12 N/A
The XML parser in Expat does not use sufficient entropy for hash initialization, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted identifiers in an XML document. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0876.
CVE-2012-6702 4 Canonical, Debian, Google and 1 more 4 Ubuntu Linux, Debian Linux, Android and 1 more 2025-04-12 N/A
Expat, when used in a parser that has not called XML_SetHashSalt or passed it a seed of 0, makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms via vectors involving use of the srand function.
CVE-2012-1148 3 Apple, Libexpat Project, Redhat 4 Mac Os X, Libexpat, Enterprise Linux and 1 more 2025-04-11 N/A
Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities.
CVE-2012-1147 2 Apple, Libexpat Project 2 Mac Os X, Libexpat 2025-04-11 N/A
readfilemap.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (file descriptor consumption) via a large number of crafted XML files.
CVE-2012-0876 6 Canonical, Debian, Libexpat Project and 3 more 15 Ubuntu Linux, Debian Linux, Libexpat and 12 more 2025-04-11 N/A
The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML file with many identifiers with the same value.
