Multiple integer overflows in tiff2pdf in libtiff before 4.0.2 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted tiff image, which triggers a heap-based buffer overflow.

The remote NewStart CGSL host, running version MAIN 6.02, has libtiff packages installed that are affected by multiple vulnerabilities:

  - Buffer overflow in the t2p_write_pdf_string function in tiff2pdf in libtiff 3.8.2 and earlier allows     attackers to cause a denial of service (crash) and possibly execute arbitrary code via a TIFF file with a     DocumentName tag that contains UTF-8 characters, which triggers the overflow when a character is sign     extended to an integer that produces more digits than expected in an sprintf call. (CVE-2006-2193)

  - Heap-based buffer overflow in the JPEG decoder in the TIFF library (libtiff) before 3.8.2 allows context-     dependent attackers to cause a denial of service and possibly execute arbitrary code via an encoded JPEG     stream that is longer than the scan line size (TiffScanLineSize). (CVE-2006-3460)

  - Heap-based buffer overflow in the PixarLog decoder in the TIFF library (libtiff) before 3.8.2 might allow     context-dependent attackers to execute arbitrary code via unknown vectors. (CVE-2006-3461)

  - Heap-based buffer overflow in the NeXT RLE decoder in the TIFF library (libtiff) before 3.8.2 might allow     context-dependent attackers to execute arbitrary code via unknown vectors involving decoding large RLE     images. (CVE-2006-3462)

  - The EstimateStripByteCounts function in TIFF library (libtiff) before 3.8.2 uses a 16-bit unsigned short     when iterating over an unsigned 32-bit value, which allows context-dependent attackers to cause a denial     of service via a large td_nstrips value, which triggers an infinite loop. (CVE-2006-3463)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.

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)

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.

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

  - Integer signedness error in the TIFFReadDirectory     function in tif_dirread.c in libtiff 3.9.4 and earlier     allows remote attackers to cause a denial of service     (application crash) and possibly execute arbitrary code     via a negative tile depth in a tiff image, which     triggers an improper conversion between signed and     unsigned types, leading to a heap-based buffer overflow.
    (CVE-2012-2088)

  - Multiple integer overflows in tiff2pdf in libtiff before     4.0.2 allow remote attackers to cause a denial of     service (application crash) or possibly execute     arbitrary code via a crafted tiff image, which triggers     a heap-based buffer overflow. (CVE-2012-2113)

- fixing multiple integer overflows :

  - CVE-2012-2113 [bnc#767852]

  - CVE-2012-2088 [bnc#767854]

New libtiff packages are available for Slackware 12.1, 12.2, 13.0, 13.1, 13.37, 14.0, and -current to fix security issues.

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)

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-1054 advisory.

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).

The following issue has been fixed :

  - Specially crafted tiff files could have caused overflows     in libtiff. (CVE-2012-2088 / CVE-2012-2113)

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.
