CVE-2013-6462: libXfont: stack-based buffer overflow flaw when parsing Glyph Bitmap Distribution Format (BDF) fonts

Severity: Critical

CVSS Score: 9.3

Stack-based buffer overflow in the bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont 1.1 through 1.4.6 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string in a character name in a BDF font file.
