The t2p_read_tiff_init function in tiff2pdf (tools/tiff2pdf.c) in LibTIFF 4.0.2 and earlier does not properly initialize the T2P context struct pointer in certain error conditions, which allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TIFF image that triggers a heap-based buffer overflow.

The remote Solaris system is missing necessary patches to address security updates :

  - The t2p_read_tiff_init function in tiff2pdf     (tools/tiff2pdf.c) in LibTIFF 4.0.2 and earlier does not     properly initialize the T2P context struct pointer in     certain error conditions, which allows context-dependent     attackers to cause a denial of service (crash) and     possibly execute arbitrary code via a crafted TIFF image     that triggers a heap-based buffer overflow.
    (CVE-2012-3401)

The following issues was fixed in tiff :

  - a overflow in tiff2pdf (CVE-2012-3401) [bnc#770816]

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).

This update of tiff fixes a heap-based buffer overflow that could have caused a crash or potentially allowed attackers to execute arbitrary code. (CVE-2012-3401)

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

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.

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.

A vulnerability was found and corrected in libtiff :

A heap-based buffer overflow flaw was found in the way tiff2pdf, a TIFF image to a PDF document conversion tool, of libtiff, a library of functions for manipulating TIFF (Tagged Image File Format) image format files, performed write of TIFF image content into particular PDF document file, when not properly initialized T2P context struct pointer has been provided by tiff2pdf (application requesting the conversion) as one of parameters for the routine performing the write.
A remote attacker could provide a specially crafted TIFF image format file, that when processed by tiff2pdf would lead to tiff2pdf executable crash or, potentially, arbitrary code execution with the privileges of the user running the tiff2pdf binary (CVE-2012-3401).

The updated packages have been patched to correct this issue.
