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.

Multiple vulnerabilities has been discovered and corrected in libtiff :

The TIFFYCbCrtoRGB function in LibTIFF 3.9.0 and 3.9.2, as used in ImageMagick, does not properly handle invalid ReferenceBlackWhite values, which allows remote attackers to cause a denial of service (application crash) via a crafted TIFF image that triggers an array index error, related to downsampled OJPEG input. (CVE-2010-2595)

Multiple integer overflows in the Fax3SetupState function in tif_fax3.c in the FAX3 decoder in LibTIFF before 3.9.3 allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted TIFF file that triggers a heap-based buffer overflow (CVE-2010-1411).

Integer overflow in the TIFFroundup macro in LibTIFF before 3.9.3 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted TIFF file that triggers a buffer overflow (CVE-2010-2065).

The TIFFRGBAImageGet function in LibTIFF 3.9.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a TIFF file with an invalid combination of SamplesPerPixel and Photometric values (CVE-2010-2483).

The TIFFVStripSize function in tif_strip.c in LibTIFF 3.9.0 and 3.9.2 makes incorrect calls to the TIFFGetField function, which allows remote attackers to cause a denial of service (application crash) via a crafted TIFF image, related to downsampled OJPEG input and possibly related to a compiler optimization that triggers a divide-by-zero error (CVE-2010-2597).

The TIFFExtractData macro in LibTIFF before 3.9.4 does not properly handle unknown tag types in TIFF directory entries, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted TIFF file (CVE-2010-248).

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.
