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 packages
Detailed Explanation for this Vulnerability Assessment
Updated kernel packages are now available as part of ongoing support and
maintenance of Red Hat Enterprise Linux version 3. This is the seventh
This security advisory has been rated as having moderate security impact
by the Red Hat Security Response Team.
The Linux kernel handles the basic functions of the operating system.
This is the seventh regular kernel update to Red Hat Enterprise Linux 3.
New features introduced by this update include:
- addition of the bnx2, dell_rbu, and megaraid_sas device drivers
- support for multi-core, multi-threaded Intel Itanium processors
- upgrade of the SATA subsystem to include ATAPI and SMART support
- optional tuning via the new numa_memory_allocator, arp_announce,
and printk_ratelimit sysctls
There were many bug fixes in various parts of the kernel. The ongoing
effort to resolve these problems has resulted in a marked improvement in
the reliability and scalability of Red Hat Enterprise Linux 3.
There were numerous driver updates and security fixes (elaborated below).
Other key areas affected by fixes in this update include the networking
subsystem, the VM subsystem, NPTL handling, autofs4, the USB subsystem,
CPU enumeration, and 32-bit-exec-mode handling on 64-bit architectures.
The following device drivers have been upgraded to new versions:
aacraid -------- 1.1.5-2412
bnx2 ----------- 1.4.30 (new)
dell_rbu ------- 2.1 (new)
e1000 ---------- 6.1.16-k3
emulex --------- 7.3.3
fusion --------- 2.06.16.02
ipmi ----------- 35.11
megaraid2 ------ v18.104.22.168
megaraid_sas --- 00.00.02.00 (new)
tg3 ------------ 3.43RH
The following security bugs were fixed in this update:
- a flaw in gzip/zlib handling internal to the kernel that permited
a local user to cause a denial of service (crash)
- a flaw in ext3 EA/ACL handling of attribute sharing that permited
a local user to gain rights (CVE-2005-2801, moderate)
- a minor info leak with the get_thread_area() syscall that permited
a local user to view uninitialized kernel stack data
Note: The kernel-unsupported package contains various drivers and modules
that are unsupported and therefore might contain security problems that
have not been addressed.
All Red Hat Enterprise Linux 3 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum.
