GLSA-200609-07 : LibXfont, monolithic X.org: Multiple integer overflows

high Nessus Plugin ID 22352

Synopsis

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

Description

The remote host is affected by the vulnerability described in GLSA-200609-07 (LibXfont, monolithic X.org: 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 X.org users are advised to migrate to modular X.org.
