Test ID:	1.3.6.1.4.1.25623.1.1.12.2005.110.1
Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-110-1)
Summary:	The remote host is missing an update for the 'linux-source-2.6.8.1' package(s) announced via the USN-110-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux-source-2.6.8.1' package(s) announced via the USN-110-1 advisory. Vulnerability Insight: Alexander Nyberg discovered an integer overflow in the sysfs_write_file() function. A local attacker could exploit this to crash the kernel or possibly even execute arbitrary code with root privileges by writing to an user-writable file in /sys under certain low-memory conditions. However, there are very few cases where a user-writeable sysfs file actually exists. (CAN-2005-0867) Olof Johansson discovered a Denial of Service vulnerability in the futex functions, which provide semaphores for exclusive locking of resources. A local attacker could possibly exploit this to cause a kernel deadlock. (CAN-2005-0937) In addition this update fixes two race conditions in the ext3 and jfs file system drivers, which could lead to a kernel crash under certain (unusual) conditions. However, these cannot easily be triggered by users, thus they are not security sensitive. ([links moved to references]) Affected Software/OS: 'linux-source-2.6.8.1' package(s) on Ubuntu 4.10. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
