Synopsis ========
A buffer overflow was discovered in the PCF font parser, potentially resulting in the execution of arbitrary code.
Background ==========
libXfont is the X.Org Xfont library, some parts are based on the FreeType code base.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-libs/libXfont < 1.2.0-r1 >= 1.2.0-r1
Description ===========
Several integer overflows have been found in the PCF font parser.
Impact ======
A local attacker could possibly execute arbitrary code or crash the Xserver by enticing a user to load a specially crafted PCF font file.
Workaround ==========
Do not use untrusted PCF Font files.
Resolution ==========
All libXfont users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-libs/libXfont-1.2.0-r1"
