CVE-2011-2895

Priority
Description
The LZW decompressor in (1) the BufCompressedFill function in
fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2)
compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8,
FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 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 attackers 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.
