K05295469: Expat vulnerability CVE-2019-15903

Security Advisory Description 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 XMLGetCurrentLineNumber or XMLGetCurrentColumnNumber then resulted in a heap-based buffer over-read. CVE-2019-15903...

K51011533: Expat XML parser vulnerability CVE-2018-20843

Security Advisory Description 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-2018-20843 Impact...

K65460334: Expat XML parser vulnerability CVE-2012-6702

Security Advisory Description Expat, when used in a parser that has not called XMLSetHashSalt 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-2012-6702 Impact An attacker m...

K70938105: Expat XML library vulnerability CVE-2016-5300

Security Advisory Description 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...

K16949: Expat vulnerabilities CVE-2012-0876 and CVE-2012-1148

Security Advisory Description CVE-2012-0876 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...

K23231802: Expat vulnerability CVE-2021-46143

Security Advisory Description In doProlog in xmlparse.c in Expat aka libexpat before 2.4.3, an integer overflow exists for mgroupSize. CVE-2021-46143 Impact A remote attacker could send specially crafted XML which, when parsed by an application using the Expat library, would result in a buffer...

K52320548: Expat vulnerability CVE-2016-0718

Security Advisory Description An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code...

K91589041: Expat vulnerabilities CVE-2021-45960, CVE-2022-22825, CVE-2022-22826, and CVE-2022-22827

Security Advisory Description CVE-2021-45960 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-2022-22825 lookup in xmlparse.c in Expat aka...

K15104541: Expat XML library vulnerability CVE-2015-1283

Security Advisory Description Multiple integer overflows in the XMLGetBuffer 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 v...

K22232964: Expat XML library vulnerability CVE-2016-4472

Security Advisory Description 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...

SUSE CVE-2009-1955

The expat XML parser in the aprxml interface in xml/aprxml.c in Apache APR-util before 1.3.7, as used in the moddav and moddavsvn modules in the Apache HTTP Server, allows remote attackers to cause a denial of service memory consumption via a crafted XML document containing a large number of nest...

SUSE CVE-2009-2473
