Synopsis: Important: libtiff security update
Issue Date: 2012-04-10
CVE Numbers: CVE-2012-1173
The libtiff packages contain a library of functions for manipulating Tagged
Image File Format (TIFF) files.
Two integer overflow flaws, leading to heap-based buffer overflows, were
found in the way libtiff attempted to allocate space for a tile in a TIFF
image file. An attacker could use these flaws 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-2012-1173)
All libtiff users should upgrade to these updated packages, which contain a
backported patch to resolve these issues. All running applications linked
against libtiff must be restarted for this update to take effect.
