CVE-2021-46143 5 Libexpat Project, Netapp, Redhat and 2 more 10 Libexpat, Active Iq Unified Manager, Clustered Data Ontap and 7 more 2024-11-21 8.1 High
In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for m_groupSize.
CVE-2021-45960 6 Debian, Libexpat Project, Netapp and 3 more 10 Debian Linux, Libexpat, Active Iq Unified Manager and 7 more 2024-11-21 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-2019-15903 3 Libexpat Project, Python, Redhat 5 Libexpat, Python, Enterprise Linux and 2 more 2024-11-21 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-2018-20843 8 Canonical, Debian, Fedoraproject and 5 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2024-11-21 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-2017-9233 3 Debian, Libexpat Project, Python 3 Debian Linux, Libexpat, Python 2024-11-21 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-2017-11742 2 Libexpat Project, Microsoft 2 Libexpat, Windows 2024-11-21 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-2016-5300 4 Canonical, Debian, Google and 1 more 4 Ubuntu Linux, Debian Linux, Android and 1 more 2024-11-21 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-2016-4472 4 Canonical, Libexpat Project, Mcafee and 1 more 4 Ubuntu Linux, Libexpat, Policy Auditor and 1 more 2024-11-21 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-2016-0718 10 Apple, Canonical, Debian and 7 more 16 Mac Os X, Ubuntu Linux, Debian Linux and 13 more 2024-11-21 9.8 Critical
Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow.
CVE-2015-1283 9 Canonical, Debian, Google and 6 more 14 Ubuntu Linux, Debian Linux, Chrome and 11 more 2024-11-21 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-2013-0340 3 Apple, Libexpat Project, Python 7 Ipados, Iphone Os, Macos and 4 more 2024-11-21 N/A
expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE.
CVE-2012-6702 4 Canonical, Debian, Google and 1 more 4 Ubuntu Linux, Debian Linux, Android and 1 more 2024-11-21 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 2024-11-21 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 2024-11-21 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 2024-11-21 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.
CVE-2009-3720 5 A M Kuchling, Apache, Libexpat Project and 2 more 7 Pyxml, Http Server, Libexpat and 4 more 2024-11-21 N/A
The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that trigger a buffer over-read, a different vulnerability than CVE-2009-2625.
CVE-2009-3560 4 Apache, Libexpat Project, Redhat and 1 more 6 Http Server, Libexpat, Enterprise Linux and 3 more 2024-11-21 N/A
The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module for Perl, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with malformed UTF-8 sequences that trigger a buffer over-read, related to the doProlog function in lib/xmlparse.c, a different vulnerability than CVE-2009-2625 and CVE-2009-3720.
CVE-2024-50602 2 Libexpat Project, Redhat 3 Libexpat, Enterprise Linux, Rhel Eus 2024-10-30 5.9 Medium
An issue was discovered in libexpat before 2.6.4. There is a crash within the XML_ResumeParser function because XML_StopParser can stop/suspend an unstarted parser.
