Updated libtiff packages that fix two security issues are now available for Red Hat Enterprise Linux 3.

The Red Hat Security Response Team has rated this update as having important 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.

Multiple integer overflow flaws, leading to a buffer overflow, were discovered in libtiff. An attacker could use these flaws 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-2010-1411)

An input validation flaw was discovered in libtiff. 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.
(CVE-2010-2598)

Red Hat would like to thank Apple Product Security for responsibly reporting the CVE-2010-1411 flaw, who credit Kevin Finisterre of digitalmunition.com for the discovery of the issue.

All libtiff users are advised to 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.

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.

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).
