Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : libpng vulnerabilities (USN-730-1)

high Nessus Plugin ID 37042
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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).

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

Solution

Update the affected libpng12-0, libpng12-dev and / or libpng3 packages.
