Test ID:1.3.6.1.4.1.25623.1.0.56196
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-244-1 (linux-source-2.6.8.1/-2.6.10/-2.6.12)
Summary:Ubuntu USN-244-1 (linux-source-2.6.8.1/-2.6.10/-2.6.12)
Description:
The remote host is missing an update to linux-source-2.6.8.1/-2.6.10/-2.6.12
announced via advisory USN-244-1.

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:
linux-image-2.6.10-6-*
linux-image-2.6.12-10-*
linux-image-2.6.8-1-*
linux-patch-debian-2.6.8.1
linux-patch-ubuntu-2.6.10
linux-patch-ubuntu-2.6.12

Doug Chapman discovered a flaw in the reference counting in the
sys_mq_open() function. By calling this function in a special way, a
local attacker could exploit this to cause a kernel crash.
(CVE-2005-3356)

Karl Janmar discovered that the /proc file system module used signed
data types in a wrong way. A local attacker could exploit this to read
random kernel memory, which could possibly contain sensitive data like
passwords or private keys. (CVE-2005-4605)

Yi Yang discovered an off-by-one buffer overflow in the sysctl()
system call. By calling sysctl with a specially crafted long string, a
local attacker could exploit this to crash the kernel or possibly even
execute arbitrary code with full kernel privileges. (CVE-2005-4618)

Perceval Anichini found a buffer overflow in the TwinHan DST
Frontend/Card DVB driver. A local user could exploit this to crash the
kernel or possibly execute arbitrary code with full kernel privileges.
This only affects Ubuntu 5.10. (CVE-2005-4639)

Stefan Rompf discovered that the dm-crypt module did not clear memory
structures before releasing the memory allocation of it. This could
lead to the disclosure of encryption keys. (CVE-2006-0095)

The SDLA WAN driver did not restrict firmware upgrades to processes
that have the CAP_SYS_RAWIO kernel capability, it just required the
CAP_NET_ADMIN privilege. This could allow processes with the latter
privilege to update the SDLA firmware. Please note that this does not
affect a standard Ubuntu installation, and this cannot be exploited by
a normal (unprivileged) user. At most, this flaw might be relevant for
installations that use a fine-grained capability granting system like
RSBAC, cap_over, or grsecurity. This only affects Ubuntu 4.10.
(CVE-2006-0096)

Solution:
The problem can be corrected by upgrading the affected package to
version 2.6.8.1-16.27 (for Ubuntu 4.10), 2.6.10-34.11 (for Ubuntu
5.04), or 2.6.12-10.26 (for Ubuntu 5.10). After a standard system
upgrade you need to reboot your computer to effect the necessary
changes.
