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 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).

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.
