|Gentoo Linux Security Advisory
Title: LibXfont: Multiple integer overflows (GLSA 200609-04)
Date: September 06, 2006
A buffer overflow was discovered in the PCF font parser, potentially resulting in the execution of arbitrary code.
libXfont is the X.Org Xfont library, some parts are based on the FreeType code base.
Vulnerable: < 1.2.0-r1
Unaffected: >= 1.2.0-r1
Architectures: All supported architectures
Several integer overflows have been found in the PCF font parser.
A local attacker could possibly execute arbitrary code or crash the Xserver by enticing a user to load a specially crafted PCF font file.
Do not use untrusted PCF Font files.
All libXfont users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/libXfont-1.2.0-r1"
