Vulnerability Assessment & Network Security Forums
If through a vulnerability assessment, a network security issue is detected for the vulnerability below, applying the appropriate security patches in a timely matter is very important. If you have detected that your system has already been compromised, following CERT's Network Security recovery document will assist with recommended steps for system recovery.
Vulnerability Assessment Details
Check for the version of the kernel package
Detailed Explanation for this Vulnerability Assessment
The remote host is missing the patch for the advisory MDKSA-2007:002 (kernel).
Some vulnerabilities were discovered and corrected in the Linux 2.6
The Linux kernel does not properly save or restore EFLAGS during a
context switch, or reset the flags when creating new threads, which
could permit a local user to cause a Denial of Service (process crash)
The seqfile handling in the 2.6 kernel up to 2.6.18 permits local users
to cause a DoS (hang or oops) via unspecified manipulations that
trigger an infinite loop while searching for flowlabels
An integer overflow in the 2.6 kernel prior to 220.127.116.11 could permit 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 permit 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 permit for overwriting
internal CMTP and CAPI data structures via malformed packets
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
- 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
