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-2007:012 (kernel).
Some vulnerabilities were discovered and corrected in the Linux 2.6
The __block_prepate_write function in the 2.6 kernel before 2.6.13 does
not properly clear buffers during certain error conditions, which
permits users to read portions of files that have been unlinked
The clip_mkip function of the ATM subsystem in the 2.6 kernel permits
remote attackers to dause a DoS (panic) via unknown vectors that cause
the ATM subsystem to access the memory of socket buffers after they are
The NFS lockd in the 2.6 kernel before 2.6.16 permits remote attackers
to cause a DoS (process crash) and deny access to NFS exports via
unspecified vectors that trigger a kernel oops and a deadlock
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
A missing call to init_timer() in the isdn_ppp code of the Linux kernel
can permit remote attackers to send a special kind of PPP pakcet which
may trigger a kernel oops (CVE-2006-5749).
An integer overflow in the 2.6 kernel prior to 188.8.131.52 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
- __bread oops fix
- added e1000_ng (nineveh support)
- added sata_svw (Broadcom SATA support)
- added Marvell PATA chipset support
- disabled mmconf on some broken hardware/BIOSes
- use GENERICARCH and enable bigsmp apic model for tulsa machines
