CVE-2009-1722 OpenEXR: Integer overflow in decompression of range of values in the pixel data
Last modified: 2016-03-04 07:12:06 EST
An integer overflow flaw, leading to heap-based buffer overflow was found in the OpenEXR's routine, decompressing range of values in the pixel data. A remote attacker provide a specially-crafted image file, which once opened, by a local, unsuspecting user, would lead to denial of service ("exrmakepreview crash") or potentially, arbitrary code execution with the privileges of user opening the image. References: ----------- http://openexr.com/ Part "Announcements" October 22, 2007 - New versions of OpenEXR and CTL are now available. This release fixes a buffer overrun in OpenEXR and a Windows build problem in CTL, and it removes a few unnecessary files from the .tar.gz packages.
This issue does NOT affect the versions of the OpenEXR package, as shipped with Fedora releases of 10 and 11. This issue affects the versions of the OpenEXR package, as shipped with the Extra Packages for Enterprise Linux 4 (EPEL4) and Extra Packages for Enterprise Linux 5 (EPEL5) projects.
