Mandriva Linux Security Advisory : libxfont (MDVSA-2011:153)

High Nessus Plugin ID 56531


The remote Mandriva Linux host is missing one or more security updates.


A vulnerability has been discovered and corrected in libxfont :

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, 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 (CVE-2011-2895).

The updated packages have been patched to correct this issue.


Update the affected packages.
