RHSA-2007-0085: kernel Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the kernel packages
Detailed Explanation for this Vulnerability Test
Updated kernel packages that fix two security issues and a bug in the Red Hat
Enterprise Linux 4 kernel are now available.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
The Linux kernel handles the basic functions of the operating system.
These new kernel packages contain fixes for two security issues:
* a flaw in the key serial number collision avoidance algorithm of the
keyctl subsystem that allowed a local user to cause a denial of service
* a flaw in the file watch implementation of the audit subsystems that
allowed a local user to cause a denial of service (panic). To exploit this
flaw a privileged user must have previously created a watch for a file
In addition to the security issues described above, a fix for the SCTP
subsystem to address a system crash which may be experienced in Telco
environments has been included.
Red Hat Enterprise Linux 4 users are advised to upgrade their kernels to
the packages associated with their machine architecture and configurations
as listed in this erratum.
