Background ========== libTIFF provides support for reading and manipulating TIFF images. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/tiff < 3.8.2-r2 >= 3.8.2-r2 Description =========== Tavis Ormandy of the Google Security Team discovered several heap and stack buffer overflows and other flaws in libTIFF. The affected parts include the TIFFFetchShortPair(), TIFFScanLineSize() and EstimateStripByteCounts() functions, and the PixarLog and NeXT RLE decoders. Impact ====== A remote attacker could entice a user to open a specially crafted TIFF file, resulting in the possible execution of arbitrary code. 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-r2" References ========== [ 1 ] CVE-2006-3459 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3459 [ 2 ] CVE-2006-3460 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3460 [ 3 ] CVE-2006-3461 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3461 [ 4 ] CVE-2006-3462 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3462 [ 5 ] CVE-2006-3463 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3463 [ 6 ] CVE-2006-3464 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3464 [ 7 ] CVE-2006-3465 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3465 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200608-07.xml 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.
