SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200801-20 (libxml2: Denial of Service)
Brad Fitzpatrick reported that the xmlCurrentChar() function does not properly handle some UTF-8 multibyte encodings.
A remote attacker could entice a user to open a specially crafted XML document with an application using libxml2, possibly resulting in a high CPU consumption. Note that this vulnerability could also be triggered without user interaction by an automated system processing XML content.
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/libxml2-2.6.30-r1'
