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 to crash or, potentially, execute arbitrary code. 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 must be restarted for the update to take effect.
