Synopsis: Moderate: libtiff security update Issue Date: 2012-12-18 CVE Numbers: CVE-2012-3401 CVE-2012-4447 CVE-2012-5581 CVE-2012-4564 -- A heap-based buffer overflow flaw was found in the way libtiff processed certain TIFF images using the Pixar Log Format encoding. An attacker could create a specially-crafted TIFF file that, when opened, could cause an application using libtiff to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2012-4447) A stack-based buffer overflow flaw was found in the way libtiff handled DOTRANGE tags. 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-2012-5581) A heap-based buffer overflow flaw was found in the tiff2pdf tool. An attacker could use this flaw to create a specially-crafted TIFF file that would cause tiff2pdf to crash or, possibly, execute arbitrary code. (CVE-2012-3401) A missing return value check flaw, leading to a heap-based buffer overflow, was found in the ppm2tiff tool. An attacker could use this flaw to create a specially-crafted PPM (Portable Pixel Map) file that would cause ppm2tiff to crash or, possibly, execute arbitrary code. (CVE-2012-4564) All running applications linked against libtiff must be restarted for this update to take effect. -- SL5 x86_64 libtiff-3.8.2-18.el5_8.i386.rpm libtiff-3.8.2-18.el5_8.x86_64.rpm libtiff-debuginfo-3.8.2-18.el5_8.i386.rpm libtiff-debuginfo-3.8.2-18.el5_8.x86_64.rpm libtiff-devel-3.8.2-18.el5_8.i386.rpm libtiff-devel-3.8.2-18.el5_8.x86_64.rpm i386 libtiff-3.8.2-18.el5_8.i386.rpm libtiff-debuginfo-3.8.2-18.el5_8.i386.rpm libtiff-devel-3.8.2-18.el5_8.i386.rpm SL6 x86_64 libtiff-3.9.4-9.el6_3.i686.rpm libtiff-3.9.4-9.el6_3.x86_64.rpm libtiff-debuginfo-3.9.4-9.el6_3.i686.rpm libtiff-debuginfo-3.9.4-9.el6_3.x86_64.rpm libtiff-devel-3.9.4-9.el6_3.i686.rpm libtiff-devel-3.9.4-9.el6_3.x86_64.rpm libtiff-static-3.9.4-9.el6_3.x86_64.rpm i386 libtiff-3.9.4-9.el6_3.i686.rpm libtiff-debuginfo-3.9.4-9.el6_3.i686.rpm libtiff-devel-3.9.4-9.el6_3.i686.rpm libtiff-static-3.9.4-9.el6_3.i686.rpm - Scientific Linux Development Team
