Integer overflow in the ReadDirectory function in tiffdump.c in tiffdump in LibTIFF before 3.9.5 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted TIFF file containing a directory data structure with many directory entries.

Specially crafted tiff files could cause a heap-based buffer overflow in the thunder- and ojpeg-decoders (CVE-2011-1167, CVE-2009-5022).

Directories with a large number of files could cause an integer overflow in the tiffdump tool (CVE-2010-4665)

From Red Hat Security Advisory 2010:0519 :

Updated libtiff packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.

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)

Multiple input validation flaws 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. (CVE-2010-2481, CVE-2010-2483, CVE-2010-2595, CVE-2010-2597)

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.

Several vulnerabilities were discovered in TIFF, a library set and tools to support the Tag Image File Format (TIFF), allowing denial of service and potential privilege escalation.

These vulnerabilities can be exploited via a specially crafted TIFF image.

  - CVE-2012-2113     The tiff2pdf utility has an integer overflow error when     parsing images.

  - CVE-2012-3401     Huzaifa Sidhpurwala discovered heap-based buffer     overflow in the t2p_read_tiff_init() function.

  - CVE-2010-2482     An invalid td_stripbytecount field is not properly     handle and can trigger a NULL pointer dereference.

  - CVE-2010-2595     An array index error, related to 'downsampled OJPEG     input' in the TIFFYCbCrtoRGB function causes an     unexpected crash.

  - CVE-2010-2597     Also related to 'downsampled OJPEG input', the     TIFFVStripSize function crash unexpectly.

  - CVE-2010-2630     The TIFFReadDirectory function does not properly     validate the data types of codec-specific tags that have     an out-of-order position in a TIFF file.

  - CVE-2010-4665     The tiffdump utility has an integer overflow in the     ReadDirectory function.

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.

Alexander Gavrun discovered that the TIFF library incorrectly allocated space for a tile. 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. (CVE-2012-1173)

It was discovered that the tiffdump utility incorrectly handled directory data structures with many directory entries. 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. This issue only applied to Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2010-4665).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The following bugs have been fixed :

  - Specially crafted files could cause a heap-based buffer     overflows in the JPEG, Fax and Thunder decoders.
    (CVE-2011-0191 / CVE-2011-0192 / CVE-2011-1167)

  - Directories with a large number of files could cause an     integer overflow in the tiffdump tool. (CVE-2010-4665)

Specially crafted tiff files could cause a heap-based buffer overflow in the thunder-decoder (CVE-2011-1167).
