| Description: | JasPer is an implementation of Part 1 of the JPEG 2000 image compression standard.
Two heap-based buffer overflow flaws were found in the way JasPer decoded JPEG 2000 compressed image files. An attacker could create a malicious JPEG 2000 compressed image file that, when opened, would cause applications that use JasPer (such as Nautilus) to crash or, potentially, execute arbitrary code. (CVE-2011-4516, CVE-2011-4517)
Red Hat would like to thank Jonathan Foote of the CERT Coordination Center for reporting these issues.
Users are advised to upgrade to these updated packages, which contain a backported patch to correct these issues. All applications using the JasPer libraries (such as Nautilus) must be restarted for the update to take effect.
