Fedora 15 : libpng10-1.0.55-1.fc15 (2011-8844)

medium Nessus Plugin ID 55654
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 Fedora host is missing a security update.

Description

This update fixes a 1-byte uninitialized memory reference in png_format_buffer(). It allows attackers to cause a denial of service (crash) via a malformed PNG image file that triggers an error that causes an out-of-bounds read when creating the error message. This is CVE-2011-2501.

Also fixed in this release are some other minor security problems and there's additionally a bugfix backported from 1.5.3: when expanding a paletted image, always expand to RGBA if transparency is present.

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.

Solution

Update the affected libpng10 package.
