Background ========== libTIFF provides support for reading and manipulating TIFF (Tag Image File Format) images. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/tiff < 3.7.2 >= 3.7.2 Description =========== Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a stack based buffer overflow in the libTIFF library when reading a TIFF image with a malformed BitsPerSample tag. Impact ====== Successful exploitation would require the victim to open a specially crafted TIFF image, resulting in the 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-3.7.2" References ========== [ 1 ] LIBTIFF BUG#863 http://bugzilla.remotesensing.org/show_bug.cgi?id=843 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200505-07.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.
