 Mandriva Linux Security Advisory                         MDKSA-2007:002
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : kernel
 Date    : January 2, 2007
 Affected: 2007.0
 _______________________________________________________________________
 
 Problem Description:
 
 Some vulnerabilities were discovered and corrected in the Linux 2.6
 kernel:

 The Linux kernel does not properly save or restore EFLAGS during a
 context switch, or reset the flags when creating new threads, which
 could allow a local user to cause a Denial of Service (process crash)
 (CVE-2006-5173).

 The seqfile handling in the 2.6 kernel up to 2.6.18 allows local users
 to cause a DoS (hang or oops) via unspecified manipulations that
 trigger an infinite loop while searching for flowlabels
 (CVE-2006-5619).

 An integer overflow in the 2.6 kernel prior to 2.6.18.4 could allow a
 local user to execute arbitrary code via a large maxnum value in an
 ioctl request (CVE-2006-5751).

 A race condition in the ISO9660 filesystem handling could allow a local
 user to cause a DoS (infinite loop) by mounting a crafted ISO9660
 filesystem containing malformed data structures (CVE-2006-5757).

 A vulnerability in the bluetooth support could allow for overwriting
 internal CMTP and CAPI data structures via malformed packets
 (CVE-2006-6106).

 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:

 - added the marvell IDE driver - use a specific driver Jmicron chipsets
 rather than using a generic one - updated the sky2 driver to fix some
 network hang issues

 To update your kernel, please follow the directions located at:
