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.
VPR Score: 8.9
SynopsisThe remote Debian host is missing a security-related update.
DescriptionA vulnerability has been discovered in the Linux kernel that may lead to privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problem :
- CVE-2009-2692 Tavis Ormandy and Julien Tinnes discovered an issue with how the sendpage function is initialized in the proto_ops structure. Local users can exploit this vulnerability to gain elevated privileges.
SolutionUpgrade the linux-2.6 and user-mode-linux packages.
For the oldstable distribution (etch), this problem will be fixed in updates to linux-2.6 and linux-2.6.24.
For the stable distribution (lenny), this problem has been fixed in version 2.6.26-17lenny2.
Note: Debian carefully tracks all known security issues across every linux kernel package in all releases under active security support.
However, given the high frequency at which low-severity security issues are discovered in the kernel and the resource requirements of doing an update, updates for lower priority issues will normally not be released for all kernels at the same time. Rather, they will be released in a staggered or 'leap-frog' fashion.
