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-2013-4520 DoS 2013-12-14 2013-12-16
4.3
None Remote Medium Not required None None Partial
xslt.c in libxslt before 1.1.25 allows context-dependent attackers to cause a denial of service (crash) via a stylesheet that embeds a DTD, which causes a structure to be accessed as a different type. NOTE: this issue is due to an incomplete fix for CVE-2012-2825.
3 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.
4 CVE-2013-1969 399 DoS Exec Code Overflow 2013-04-25 2013-06-20
7.5
None Remote Low Not required Partial Partial Partial
Multiple use-after-free vulnerabilities in libxml2 2.9.0 and possibly other versions might allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to the (1) htmlParseChunk and (2) xmldecl_done functions, as demonstrated by a buffer overflow in the xmlBufGetInputBase function.
5 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.
6 CVE-2013-0338 119 DoS Overflow 2013-04-25 2014-01-23
4.3
None Remote Medium Not required None None Partial
