Background ========= libTIFF provides support for reading and manipulating TIFF (Tagged Image File Format) images. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/tiff < 3.8.2-r8 > = 3.8.2-r8 Description ========== 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. Resolution ========= All libTIFF users should upgrade to the latest version: #emerge --sync # emerge --ask --oneshot --verbose "> =media-libs/tiff-3.8.2-r8" References ========= [ 1 ] CVE-2009-2285 https://www.cve.org/CVERecord?id=CVE-2009-2285 [ 2 ] CVE-2009-2347 https://www.cve.org/CVERecord?id=CVE-2009-2347 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200908-03 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
