(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."
