RHSA-2010:0661: Important: kernel security update
First published: Mon Aug 30 2010(Updated: )
The kernel packages contain the Linux kernel, the core of any Linux<br>operating system.<br>This update fixes the following security issue:<br><li> when an application has a stack overflow, the stack could silently</li> overwrite another memory mapped area instead of a segmentation fault<br>occurring, which could cause an application to execute arbitrary code,<br>possibly leading to privilege escalation. It is known that the X Window<br>System server can be used to trigger this flaw. (CVE-2010-2240, Important)<br>Red Hat would like to thank the X.Org security team for reporting this<br>issue. Upstream acknowledges Rafal Wojtczuk as the original reporter.<br>Users should upgrade to these updated packages, which contain backported<br>patches to correct this issue. The system must be rebooted for this update<br>to take effect.<br>
