Scientific Linux Security Update : libtiff on SL4.x i386/x86_64
Medium Nessus Plugin ID 60999
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionA heap-based buffer overflow flaw was found in the way libtiff processed certain TIFF files encoded with a 4-bit run-length encoding scheme from ThunderScan. An attacker could use this flaw to create a specially crafted TIFF file that, when opened, would cause an application linked against libtiff to crash or, possibly, execute arbitrary code. (CVE-2011-1167)
This update also fixes the following bug :
- A prior libtiff update introduced a regression that prevented certain TIFF Internet Fax image files, compressed with the CCITT Group 4 compression algorithm, from being read. (BZ#688825)
SolutionUpdate the affected libtiff and / or libtiff-devel packages.
