1 CVE-2014-3660 DoS 2014-11-04 2014-11-13
5.0
None Remote Low Not required None None Partial
parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML document containing a large number of nested entity references, a variant of the "billion laughs" attack.
2 CVE-2013-2877 119 DoS Overflow 2013-07-10 2014-01-23
5.0
None Remote Low Not required None None Partial
parser.c in libxml2 before 2.9.0, as used in Google Chrome before 28.0.1500.71 and other products, allows remote attackers to cause a denial of service (out-of-bounds read) via a document that ends abruptly, related to the lack of certain checks for the XML_PARSER_EOF state.
3 CVE-2013-0339 264 DoS 2014-01-21 2014-01-22
6.8
None Remote Medium Not required Partial Partial Partial
libxml2 through 2.9.1 does not properly handle external entities expansion unless an application developer uses the xmlSAX2ResolveEntity or xmlSetExternalEntityLoader 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 libxml2 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.
4 CVE-2013-0338 119 DoS Overflow 2013-04-25 2014-01-23
4.3
None Remote Medium Not required None None Partial
libxml2 2.9.0 and earlier allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via an XML file containing an entity declaration with long replacement text and many references to this entity, aka "internal entity expansion" with linear complexity.
5 CVE-2012-5134 119 DoS Exec Code Overflow 2012-11-27 2014-01-27
6.8
None Remote Medium Not required Partial Partial Partial
Heap-based buffer underflow in the xmlParseAttValueComplex function in parser.c in libxml2 2.9.0 and earlier, as used in Google Chrome before 23.0.1271.91 and other products, allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted entities in an XML document.
6 CVE-2012-0841 399 DoS 2012-12-21 2014-01-27
5.0
None Remote Low Not required None None Partial
libxml2 before 2.8.0 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 crafted XML data.
7 CVE-2011-1944 189 DoS Exec Code Overflow 2011-09-02 2013-02-06
9.3
None Remote Medium Not required Complete Complete Complete
Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions.
8 CVE-2010-4008 119 DoS Overflow 2010-11-16 2014-11-13
4.3
None Remote Medium Not required None None Partial
libxml2 before 2.7.8, as used in Google Chrome before 7.0.517.44, Apple Safari 5.0.2 and earlier, and other products, reads from invalid memory locations during processing of malformed XPath expressions, which allows context-dependent attackers to cause a denial of service (application crash) via a crafted XML document.
9 CVE-2009-2416 399 DoS 2009-08-11 2014-10-24
4.3
None Remote Medium Not required None None Partial
Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework.
10 CVE-2009-2414 119 DoS Overflow 2009-08-11 2014-10-24
4.3
None Remote Medium Not required None None Partial
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.
11 CVE-2008-3529 119 1 DoS Exec Code Overflow 2008-09-12 2010-08-21
10.0
Admin Remote Low Not required Complete Complete Complete
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.
