GLSA-201202-09 : libxml2: User-assisted execution of arbitrary code
High Nessus Plugin ID 58175
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201202-09 (libxml2: User-assisted execution of arbitrary code)
The 'xmlStringLenDecodeEntities()' function in parser.c contains a boundary error which could possibly cause a heap-based buffer overflow.
A remote attacker could entice a user to open a specially crafted XML file in an application linked against libxml2, possibly resulting in the remote execution of arbitrary code with the permissions of the user running the application, or Denial of Service.
There is no known workaround at this time.
SolutionAll libxml2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/libxml2-2.7.8-r4' Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
