Mandriva Linux Security Advisory MDVSA-2013:046
Package : libtiff
Date : April 5, 2013
Affected: Business Server 1.0
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).
Huzaifa Sidhpurwala discovered that the tiff2pdf utility incorrectly
handled certain malformed TIFF images. If a user or automated
system were tricked into opening a specially crafted TIFF image,
a remote attacker could crash the application, leading to a denial
of service, or possibly execute arbitrary code with user privileges
It was discovered that a buffer overflow in libtiff's parsing of files
using PixarLog compression could lead to the execution of arbitrary
ppm2tiff does not check the return value of the TIFFScanlineSize
function, which allows remote attackers to cause a denial of service
(crash) and possibly execute arbitrary code via a crafted PPM image
that triggers an integer overflow, a zero-memory allocation, and a
heap-based buffer overflow (CVE-2012-4564).
It was discovered that LibTIFF incorrectly handled certain malformed
images using the DOTRANGE tag. If a user or automated system were
tricked into opening a specially crafted TIFF image, a remote attacker
could crash the application, leading to a denial of service, or
possibly execute arbitrary code with user privileges (CVE-2012-5581).
