Denial of service while decompressing a highly compressed huge ancillary chunk has been fixed in libpng. CVE-2010-0205 has been assigned.

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.

A memory corruption flaw was found in the way applications, using the libpng library and its progressive reading method, decoded certain PNG images. An attacker could create a specially crafted PNG image that, when opened, could cause an application using libpng to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2010-1205)

A denial of service flaw was found in the way applications using the libpng library decoded PNG images that have certain, highly compressed ancillary chunks. An attacker could create a specially crafted PNG image that could cause an application using libpng to consume excessive amounts of memory and CPU time, and possibly crash.
(CVE-2010-0205)

A memory leak flaw was found in the way applications using the libpng library decoded PNG images that use the Physical Scale (sCAL) extension. An attacker could create a specially crafted PNG image that could cause an application using libpng to exhaust all available memory and possibly crash or exit. (CVE-2010-2249)

A sensitive information disclosure flaw was found in the way applications using the libpng library processed 1-bit interlaced PNG images. An attacker could create a specially crafted PNG image that could cause an application using libpng to disclose uninitialized memory. (CVE-2009-2042)

Users of libpng and libpng10 should upgrade to these updated packages, which contain backported patches to correct these issues. All running applications using libpng or libpng10 must be restarted for the update to take effect.

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.

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.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2010-387:01 advisory.

    The libpng package contains a library of functions for creating and manipulating PNG (Portable Network     Graphics) image format files.  PNG is a bit-mapped graphics format similar to the GIF format.  PNG was     created to replace the GIF format, since GIF uses a patented data compression algorithm.
    Libpng should be installed if you need to manipulate PNG format image     Security issues fixed with this release:
    CVE-2009-2042     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-2010-0205     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-2010-1205     Buffer overflow in pngpread.c in libpng before 1.2.44 and 1.4.x before 1.4.3, as used in progressive     applications, might allow remote attackers to execute arbitrary code via a PNG image that triggers an     additional data row.
    CVE-2010-2249     Memory leak in pngrutil.c in libpng before 1.2.44, and 1.4.x before 1.4.3, allows remote attackers to     cause a denial of service (memory consumption and application crash) via a PNG image containing malformed     Physical Scale (aka sCAL) chunks.

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.

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
