Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200609-07
(LibXfont, monolithic Multiple integer overflows)

Several integer overflows have been found in the CID font parser.

Impact :

A remote attacker could exploit this vulnerability by enticing a user
to load a malicious font file resulting in the execution of arbitrary
code with the permissions of the user running the X server which
typically is the root user. A local user could exploit this
vulnerability to gain elevated privileges.

Workaround :

Disable CID-encoded Type 1 fonts by removing the 'type1' module and
replacing it with the 'freetype' module in xorg.conf.

Solution :

All libXfont users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=x11-libs/libXfont-1.2.1'
All monolithic users are advised to migrate to modular
