Fedora 14 : libpng10-1.0.55-1.fc14 (2011-8867)

Medium Nessus Plugin ID 55655


The remote Fedora host is missing a security update.


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.


Update the affected libpng10 package.
