The png_decompress_chunk function in pngrutil.c in libpng 1.0.x before 1.0.53, 1.2.x before 1.2.43, and 1.4.x before 1.4.1 does not properly handle compressed ancillary-chunk data that has a disproportionately large uncompressed representation, which allows remote attackers to cause a denial of service (memory and CPU consumption, and application hang) via a crafted PNG file, as demonstrated by use of the deflate compression method on data composed of many occurrences of the same character, related to a "decompression bomb" attack.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2010-0534 advisory.

The remote host is affected by the vulnerability described in GLSA-201010-01 (Libpng: Multiple vulnerabilities)

    Multiple vulnerabilities were found in libpng:
      The png_decompress_chunk() function in pngrutil.c does not properly         handle certain type of compressed data (CVE-2010-0205)       A buffer overflow in pngread.c when using progressive applications         (CVE-2010-1205)       A memory leak in pngrutil.c when dealing with a certain type of         chunks (CVE-2010-2249)   Impact :

    An attacker could exploit these vulnerabilities to cause programs linked       against the library to crash or execute arbitrary code with the       permissions of the user running the vulnerable program, which could be       the root user.
  Workaround :

    There is no known workaround at this time.

Updated libpng and libpng10 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3, 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 libpng packages contain a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.

Update to libpng 1.2.43, includes fix for CVE-2010-0205

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

This is the latest upstream maintenance release. In addition to a number of minor bugfixes, it mitigates the resource-consumption effects of highly compressed ancillary chunks in hostile PNG files as described at http://libpng.sourceforge.net/ADVISORY-1.4.1.html This issue has been assigned CVE-2010-0205 by CERT.

A vulnerability in libpng can result in denial of service conditions when a remote attacker tricks a victim to open a specially crafted PNG file.

The PNG project describes the problem in an advisory :

Because of the efficient compression method used in Portable Network Graphics (PNG) files, a small PNG file can expand tremendously, acting as a 'decompression bomb'.

Malformed PNG chunks can consume a large amount of CPU and wall-clock time and large amounts of memory, up to all memory available on a system

Several vulnerabilities have been discovered in libpng, a library for reading and writing PNG files. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-2042     libpng does not properly parse 1-bit interlaced images     with width values that are not divisible by 8, which     causes libpng to include uninitialized bits in certain     rows of a PNG file and might allow remote attackers to     read portions of sensitive memory via 'out-of-bounds     pixels' in the file.

  - CVE-2010-0205     libpng does not properly handle compressed     ancillary-chunk data that has a disproportionately large     uncompressed representation, which allows remote     attackers to cause a denial of service (memory and CPU     consumption, and application hang) via a crafted PNG     file

A vulnerability has been found and corrected in libpng :

The png_decompress_chunk function in pngrutil.c in libpng 1.0.x before 1.0.53, 1.2.x before 1.2.43, and 1.4.x before 1.4.1 does not properly handle compressed ancillary-chunk data that has a disproportionately large uncompressed representation, which allows remote attackers to cause a denial of service (memory and CPU consumption, and application hang) via a crafted PNG file, as demonstrated by use of the deflate compression method on data composed of many occurrences of the same character, related to a decompression bomb attack (CVE-2010-0205).

The updated packages have been patched to correct this issue.

Multiple vulnerabilities has been found and corrected in libpng :

libpng before 1.2.37 does not properly parse 1-bit interlaced images with width values that are not divisible by 8, which causes libpng to include uninitialized bits in certain rows of a PNG file and might allow remote attackers to read portions of sensitive memory via out-of-bounds pixels in the file (CVE-2009-2042).

The png_decompress_chunk function in pngrutil.c in libpng 1.0.x before 1.0.53, 1.2.x before 1.2.43, and 1.4.x before 1.4.1 does not properly handle compressed ancillary-chunk data that has a disproportionately large uncompressed representation, which allows remote attackers to cause a denial of service (memory and CPU consumption, and application hang) via a crafted PNG file, as demonstrated by use of the deflate compression method on data composed of many occurrences of the same character, related to a decompression bomb attack (CVE-2010-0205).

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers.

The updated packages have been patched to correct these issues.

It was discovered that libpng did not properly initialize memory when decoding certain 1-bit interlaced images. If a user or automated system were tricked into processing crafted PNG images, an attacker could possibly use this flaw to read sensitive information stored in memory. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 8.10 and 9.04. (CVE-2009-2042)

It was discovered that libpng did not properly handle certain excessively compressed PNG images. If a user or automated system were tricked into processing a crafted PNG image, an attacker could possibly use this flaw to consume all available resources, resulting in a denial of service. (CVE-2010-0205).
