SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak. The Common Vulnerabilities and Exposures project identifies the following problems :
- CVE-2010-2492 Andre Osterhues reported an issue in the eCryptfs subsystem. A buffer overflow condition may allow local users to cause a denial of service or gain elevated privileges.
- CVE-2010-2954 Tavis Ormandy reported an issue in the irda subsystem which may allow local users to cause a denial of service via a NULL pointer dereference.
- CVE-2010-3078 Dan Rosenberg discovered an issue in the XFS file system that allows local users to read potentially sensitive kernel memory.
- CVE-2010-3080 Tavis Ormandy reported an issue in the ALSA sequencer OSS emulation layer. Local users with sufficient privileges to open /dev/sequencer (by default on Debian, this is members of the 'audio' group) can cause a denial of service via a NULL pointer dereference.
- CVE-2010-3081 Ben Hawkes discovered an issue in the 32-bit compatibility code for 64-bit systems. Local users can gain elevated privileges due to insufficient checks in compat_alloc_user_space allocations.
SolutionUpgrade the linux-2.6 and user-mode-linux packages.
For the stable distribution (lenny), this problem has been fixed in version 2.6.26-25lenny1.
