GLSA-201207-02 : libxml2: User-assisted execution of arbitrary code
Medium Nessus Plugin ID 59894
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201207-02 (libxml2: User-assisted execution of arbitrary code)
The 'xmlXPtrEvalXPtrPart()' function in xpointer.c contains an off-by-one error.
A remote attacker could entice a user or automated system to open a specially crafted XML document with an application using libxml2, possibly resulting in execution of arbitrary code or a Denial of Service condition.
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/libxml2-2.8.0_rc1'
