2009-08-11

Not applicable

No public exploit

Stack consumption vulnerability in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allows context-dependent attackers to cause a denial of service (application crash) via a large depth of element declarations in a DTD, related to a function recursion, as demonstrated by the Codenomicon XML fuzzing framework.

CVE-2008-4226

High

2008-11-25

Not applicable

No public exploit

CVE-2008-4409

Medium

2008-10-03

Not applicable

Working exploit published

libxml2 2.7.0 and 2.7.1 does not properly handle "predefined entities definitions" in entities, which allows context-dependent attackers to cause a denial of service (memory consumption and application crash), as demonstrated by use of xmllint on a certain XML document, a different vulnerability than CVE-2003-1564 and CVE-2008-3281.

CVE-2008-3529

High

2008-09-12

Not applicable

Working exploit published

Heap-based buffer overflow in the xmlParseAttValueComplex function in parser.c in libxml2 before 2.7.0 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a long XML entity name.

CVE-2008-3281

Medium

2008-08-27

Not applicable

No public exploit
