Details

It was discovered that libXfont incorrectly handled certain malformed BDF
fonts. An attacker could use a specially crafted font file to cause
libXfont to crash, or possibly execute arbitrary code in order to gain
privileges. The default compiler options for affected releases should
reduce the vulnerability to a denial of service.
