The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont prior to 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD prior to 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x prior to 5.0.3 and 5.1.x prior to 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent malicious users to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896.
