MGASA-2012-0137
Date: 	July 9th, 2012
Affected releases: 	1, 2


Description:
Updated libtiff packages fix security vulnerabilities:

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).
