Detail

Synopsis

Multiple vulnerabilities have been found in libxml2, the worst of which could result in the execution of arbitrary code.

Background

libxml2 is the XML (eXtended Markup Language) C parser and toolkit initially developed for the Gnome project.

Description

Multiple vulnerabilities have been discovered in libxml2. Please review the CVE identifiers referenced below for details.

Impact

A remote attacker, by enticing a user to process a specially crafted XML document, could remotely execute arbitrary code, conduct XML External Entity (XXE) attacks, or cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All libxml2 users should upgrade to the latest version:

Â
# emerge --sync
Â
# emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.9.4-r3"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
