Heap-based buffer overflow in tif_pixarlog.c in LibTIFF before 4.0.3 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted TIFF image using the PixarLog Compression format.

This update of tiff fixed a heap-based buffer overflow vulnerability and an integer overflow issue.

The remote host is affected by the vulnerability described in GLSA-201402-21 (libTIFF: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libTIFF. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted TIFF       file with an application making use of libTIFF, possibly resulting in       execution of arbitrary code with the privileges of the user running the       application or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

New libtiff packages are available for Slackware 12.1, 12.2, 13.0, 13.1, 13.37, 14.0, and -current to fix security issues.

A heap-based buffer overflow flaw was found in the way libtiff processed certain TIFF images using the Pixar Log Format encoding. An attacker could create a specially crafted TIFF file that, when opened, could cause an application using libtiff to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2012-4447)

A stack-based buffer overflow flaw was found in the way libtiff handled DOTRANGE tags. 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-2012-5581)

A heap-based buffer overflow flaw was found in the tiff2pdf tool. An attacker could use this flaw to create a specially crafted TIFF file that would cause tiff2pdf to crash or, possibly, execute arbitrary code. (CVE-2012-3401)

A missing return value check flaw, leading to a heap-based buffer overflow, was found in the ppm2tiff tool. An attacker could use this flaw to create a specially crafted PPM (Portable Pixel Map) file that would cause ppm2tiff to crash or, possibly, execute arbitrary code.
(CVE-2012-4564)

From Red Hat Security Advisory 2012:1590 :

Updated libtiff packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

(CVE-2012-4564)

The CVE-2012-5581, CVE-2012-3401, and CVE-2012-4564 issues were discovered by Huzaifa Sidhpurwala of the Red Hat Security Response Team.

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.

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).

The version of BlackBerry Enterprise Server on the remote host reportedly contains multiple remote code execution vulnerabilities in its image processing library :

  - The 'TIFFReadDirectory()' function in 'tif_dirread.c'     is affected by a buffer overflow vulnerability that can     be triggered via a specially crafted TIFF image,     potentially leading to arbitrary code execution.
    (CVE-2012-2088)

  - A flaw in handling PixarLog compressed TIFF images may     be triggered via a specially crafted TIFF image,     potentially leading to arbitrary code execution.
    (CVE-2012-4447)

Various memory corruption vulnerabilities have been fixed in libtiff.
CVE-2012-4447 / CVE-2012-4564 / CVE-2012-5581 have been assigned to these issues.

Add upstream patches for CVE-2012-4447, CVE-2012-4564 (note:
CVE-2012-5581 is already fixed in 4.0.3)
