A vulnerability has been found and corrected in libtiff :

libtiff allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a crafted TIFF image (CVE-2010-3087).

The updated packages have been patched to correct this issue.

specially crafted tiff files could cause a memory corruption in libtiff. Attackers could potentially exploit that to execute arbitrary code in applications that use libtiff for processing tiff files (CVE-2010-3087).

Sauli Pahlman discovered that the TIFF library incorrectly handled invalid td_stripbytecount fields. 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. This issue only affected Ubuntu 10.04 LTS and 10.10. (CVE-2010-2482)

Sauli Pahlman discovered that the TIFF library incorrectly handled TIFF files with an invalid combination of SamplesPerPixel and Photometric values. 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. This issue only affected Ubuntu 10.10. (CVE-2010-2482)

Nicolae Ghimbovschi discovered that the TIFF library incorrectly handled invalid ReferenceBlackWhite values. 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. (CVE-2010-2595)

Sauli Pahlman discovered that the TIFF library incorrectly handled certain default fields. 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. (CVE-2010-2597, CVE-2010-2598)

It was discovered that the TIFF library incorrectly validated certain data types. 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. (CVE-2010-2630)

It was discovered that the TIFF library incorrectly handled downsampled JPEG data. If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could execute arbitrary code with user privileges, or crash the application, leading to a denial of service. This issue only affected Ubuntu 10.04 LTS and 10.10. (CVE-2010-3087)

It was discovered that the TIFF library incorrectly handled certain JPEG data. If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could execute arbitrary code with user privileges, or crash the application, leading to a denial of service. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS and 9.10. (CVE-2011-0191)

It was discovered that the TIFF library incorrectly handled certain TIFF FAX images. If a user or automated system were tricked into opening a specially crafted TIFF FAX image, a remote attacker could execute arbitrary code with user privileges, or crash the application, leading to a denial of service. (CVE-2011-0191).

The remote host is affected by the vulnerability described in GLSA-201209-02 (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.

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

  - An unspecified error within the BlackBerry MDS     Connection Service when processing PNG and TIFF images     on a web page being viewed on a BlackBerry smartphone.

  - An unspecified error within the BlackBerry Messaging     Agent when processing embedded PNG and TIFF images in     an email sent to a BlackBerry smartphone.

When the image processing library is used on a specially crafted PNG or TIFF image, an attacker may be able to execute arbitrary code in the context of the BlackBerry Enterprise Server login account.

USN-1085-1 fixed vulnerabilities in the system TIFF library. The upstream fixes were incomplete and created problems for certain CCITTFAX4 files. This update fixes the problem.

We apologize for the inconvenience.
