GLSA-200908-03 : libTIFF: User-assisted execution of arbitrary code

High Nessus Plugin ID 40519


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200908-03 (libTIFF: User-assisted execution of arbitrary code)

Two vulnerabilities have been reported in libTIFF:
wololo reported a buffer underflow in the LZWDecodeCompat() function (CVE-2009-2285).
Tielei Wang of ICST-ERCIS, Peking University reported two integer overflows leading to heap-based buffer overflows in the tiff2rgba and rgb2ycbcr tools (CVE-2009-2347).
Impact :

A remote attacker could entice a user to open a specially crafted TIFF file with an application making use of libTIFF or the tiff2rgba and rgb2ycbcr tools, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
Workaround :

There is no known workaround at this time.


All libTIFF users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/tiff-3.8.2-r8'
