CVE-2022-43680 4 Debian, Fedoraproject, Libexpat Project and 1 more 18 Debian Linux, Fedora, Libexpat and 15 more 2024-01-03 N/A 7.5 HIGH
In libexpat through 2.4.9, there is a use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate in out-of-memory situations.
CVE-2017-9233 3 Debian, Libexpat Project, Python 3 Debian Linux, Libexpat, Python 2022-07-28 5.0 MEDIUM 7.5 HIGH
XML External Entity vulnerability in libexpat 2.2.0 and earlier (Expat XML Parser Library) allows attackers to put the parser in an infinite loop using a malformed external entity definition from an external DTD.
CVE-2019-15903 2 Libexpat Project, Python 2 Libexpat, Python 2022-07-28 5.0 MEDIUM 7.5 HIGH
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
CVE-2021-45960 4 Debian, Libexpat Project, Netapp and 1 more 7 Debian Linux, Libexpat, Active Iq Unified Manager and 4 more 2022-07-12 9.0 HIGH 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-2016-4472 4 Canonical, Libexpat Project, Mcafee and 1 more 4 Ubuntu Linux, Libexpat, Policy Auditor and 1 more 2022-07-05 6.8 MEDIUM 8.1 HIGH
The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.
CVE-2022-25314 4 Debian, Fedoraproject, Libexpat Project and 1 more 5 Debian Linux, Fedora, Libexpat and 2 more 2022-06-14 5.0 MEDIUM 7.5 HIGH
In Expat (aka libexpat) before 2.4.5, there is an integer overflow in copyString.
CVE-2022-22825 2 Libexpat Project, Tenable 2 Libexpat, Nessus 2022-06-14 6.8 MEDIUM 8.8 HIGH
lookup in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
CVE-2022-22826 2 Libexpat Project, Tenable 2 Libexpat, Nessus 2022-06-14 6.8 MEDIUM 8.8 HIGH
nextScaffoldPart in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
CVE-2022-22827 2 Libexpat Project, Tenable 2 Libexpat, Nessus 2022-06-14 6.8 MEDIUM 8.8 HIGH
storeAtts in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
CVE-2021-46143 3 Libexpat Project, Netapp, Tenable 5 Libexpat, Clustered Data Ontap, Oncommand Workflow Automation and 2 more 2022-06-14 6.8 MEDIUM 7.8 HIGH
In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for m_groupSize.
CVE-2018-20843 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2021-10-20 7.8 HIGH 7.5 HIGH
In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks).
CVE-2016-5300 4 Canonical, Debian, Google and 1 more 4 Ubuntu Linux, Debian Linux, Android and 1 more 2021-07-31 7.8 HIGH 7.5 HIGH
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-2017-11742 2 Libexpat Project, Microsoft 2 Libexpat, Windows 2017-08-09 4.6 MEDIUM 7.8 HIGH
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.
