Summary

The key serial number collision avoidance code in the key_alloc_serial function in Linux kernel 2.6.9 up to 2.6.20 allows local users to cause a denial of service (crash) via vectors that trigger a null dereference, as originally reported as "spinlock CPU recursion."

    descriptionUpdated 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 (CVE-2007-0006, Important) * 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 (CVE-2007-0001, Moderate) 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.

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 (CVE-2007-0006, Important) * 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 (CVE-2007-0001, Moderate) 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.

"From Red Hat Security Advisory 2007:0085 :

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 (CVE-2007-0006, Important)

* 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 (CVE-2007-0001, Moderate)

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."

    descriptionSome vulnerabilities were discovered and corrected in the Linux 2.6 kernel : A double free vulnerability in the squashfs module could allow a local user to cause a Denial of Service by mounting a crafted squashfs filesystem (CVE-2006-5701). The zlib_inflate function allows local users to cause a crash via a malformed filesystem that uses zlib compression that triggers memory corruption (CVE-2006-5823). The key serial number collision avoidance code in the key_alloc_serial function in kernels 2.6.9 up to 2.6.20 allows local users to cause a crash via vectors thatr trigger a null dereference (CVE-2007-0006). The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels immediately and reboot to effect the fixes. In addition to these security fixes, other fixes have been included such as : - New drivers: nozomi, UVC - Fixed SiS SATA support for chips on 966/968 bridges - Fixed issues in squashfs by updating to 3.2 (#27008) - Added support for SiS968 bridgest to the sis190 bridge - Fixed JMicron cable detection - Added /proc/config.gz support and enabled kexec on x86_64 - Other minor fixes To update your kernel, please follow the directions located at : http://www.mandriva.com/en/security/kernelupdate
