Mandriva Linux Security Advisory : libtiff (MDVSA-2013:046)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

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).

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
(CVE-2012-3401).

It was discovered that a buffer overflow in libtiff's parsing of files
using PixarLog compression could lead to the execution of arbitrary
code (CVE-2012-4447).

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).

Solution :

Update the affected packages.
