1 CVE-2013-0340 264 DoS 2014-01-21 2014-01-22
6.8
None Remote Medium Not required Partial Partial Partial
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.
2 CVE-2012-1148 399 DoS 2012-07-03 2013-06-25
5.0
None Remote Low Not required None None Partial
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.
3 CVE-2012-1147 20 DoS 2012-07-03 2013-06-25
4.3
None Remote Medium Not required None None Partial
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.
4 CVE-2012-0876 399 DoS 2012-07-03 2013-10-30
4.3
None Remote Medium Not required None None Partial
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.
