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.

Security readout for executives and security teams

CVE-2013-6462 is a memory corruption flaw in X.Org libXfont. A specially crafted BDF font file with an overly long character name can crash software using the library and may allow arbitrary code execution. The issue is old, but still matters where legacy Linux or Unix graphical/font components remain unpatched. Exposure is most likely on legacy systems running affected libXfont versions, especially where X.Org font handling or applications can load BDF fonts from untrusted users, packages, or network-supplied content. Prioritize remediation for legacy graphical servers, desktops, kiosks, appliances, or multi-user Unix systems. This is not shown as actively exploited in the provided sources, but the potential impact includes service crash and possible code execution. Mitigation focus: Apply vendor security updates from the relevant Linux or Unix distribution.; Confirm libXfont is newer than affected versions 1.1 through 1.4.6.; Restrict acceptance or loading of untrusted BDF font files where patching is delayed..
