New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

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.
The following matrix lists additional source packages that were rebuilt for compatibility with or to take advantage of this update :
Debian 5.0 (lenny) user-mode-linux 2.6.26-1um-2+25lenny1
