4.105. jasper
Updated jasper packages that fix two security issues are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) associated with each description below.
JasPer is an implementation of Part 1 of the JPEG 2000 image compression standard.
Security Fix
- CVE-2011-4516, CVE-2011-4517
- 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.
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.
