Synopsis: Important: libtiff security update
Issue Date: 2012-07-03
CVE Numbers: CVE-2012-2113
 CVE-2012-2088

The libtiff packages contain a library of functions for manipulating Tagged
Image File Format (TIFF) files.

libtiff did not properly convert between signed and unsigned integer
values, leading to a buffer overflow. 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-2012-2088)

Multiple integer overflow flaws, leading to heap-based buffer overflows,
were found in the tiff2pdf tool. An attacker could use these flaws to
create a specially-crafted TIFF file that would cause tiff2pdf to crash or,
possibly, execute arbitrary code. (CVE-2012-2113)

All libtiff users should upgrade to these updated packages, which contain
backported patches to resolve these issues. All running applications linked
against libtiff must be restarted for this update to take effect.
