Ubuntu Security Notice USN-730-1             March 06, 2009
libpng vulnerabilities
CVE-2007-5268, CVE-2007-5269, CVE-2008-1382, CVE-2008-3964,
CVE-2008-5907, CVE-2009-0040
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 7.10
Ubuntu 8.04 LTS
Ubuntu 8.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  libpng12-0                      1.2.8rel-5ubuntu0.4

Ubuntu 7.10:
  libpng12-0                      1.2.15~beta5-2ubuntu0.2

Ubuntu 8.04 LTS:
  libpng12-0                      1.2.15~beta5-3ubuntu0.1

Ubuntu 8.10:
  libpng12-0                      1.2.27-1ubuntu0.1

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.

Details follow:

It was discovered that libpng did not properly perform bounds checking in
certain operations. An attacker could send a specially crafted PNG image and
cause a denial of service in applications linked against libpng. This issue
only affected Ubuntu 8.04 LTS. (CVE-2007-5268, CVE-2007-5269)

Tavis Ormandy discovered that libpng did not properly initialize memory. If a
user or automated system were tricked into opening a crafted PNG image, an
attacker could cause a denial of service via application crash, or possibly
execute arbitrary code with the privileges of the user invoking the program.
This issue did not affect Ubuntu 8.10. (CVE-2008-1382)

Harald van Dijk discovered an off-by-one error in libpng. An attacker could
could cause an application crash in programs using pngtest. (CVE-2008-3964)

It was discovered that libpng did not properly NULL terminate a keyword
string. An attacker could exploit this to set arbitrary memory locations to
zero. (CVE-2008-5907)

Glenn Randers-Pehrson discovered that libpng did not properly initialize
pointers. If a user or automated system were tricked into opening a crafted PNG
file, an attacker could cause a denial of service or possibly execute arbitrary
code with the privileges of the user invoking the program. (CVE-2009-0040)
