The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly handle character bitmaps it cannot read, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) and possibly execute arbitrary code via a crafted BDF font file.

Security readout for executives and security teams

CVE-2015-1803 is a bug in X.Org libXfont’s BDF font parsing. A crafted bitmap font can crash a service or, according to the CVE text, possibly lead to code execution. The known attack condition is remote authenticated access, so urgency depends on whether systems accept or load user-supplied BDF fonts. Exposure is most likely on systems or products shipping vulnerable X.Org libXfont packages, especially where authenticated users can provide or trigger loading of BDF font files. The bundle cites multiple Linux and Unix vendor advisories, but does not provide a complete affected-product inventory. Handle through normal vulnerability management unless exposed workflows allow authenticated users to upload or load fonts. The main confirmed impact is service crash, with possible code execution noted but not evidenced in the bundle. Patch older systems that still carry vulnerable X.Org packages. Mitigation focus: Upgrade libXfont to 1.4.9, 1.5.1, or a vendor-patched package.; Apply relevant distro advisories from Debian, Ubuntu, Red Hat, Fedora, Gentoo, SUSE, or Oracle.; Limit who can submit or load BDF fonts until patched..
