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 is different from CVSS.

SynopsisThe remote SuSE 11 host is missing one or more security updates.
DescriptionThe SUSE Linux Enterprise 11 SP1 kernel has been updated to the 18.104.22.168 stable release to fix a lot of bugs and security issues.
The following security issues have been fixed :
- A use after free bug in hugetlb support could be used by local attackers to crash the system. (CVE-2012-2133)
- A NULL pointer dereference bug in the regsets proc file could be used by local attackers to perhaps crash the system. With mmap_min_addr is set and enabled, exploitation is unlikely. (CVE-2012-1097)
- A reference counting issue in CLONE_IO could be used by local attackers to cause a denial of service (out of memory). (CVE-2012-0879)
- A file handle leak in CIFS code could be used by local attackers to crash the system. (CVE-2012-1090)
- Large nested epoll chains could be used by local attackers to cause a denial of service (excessive CPU consumption). (CVE-2011-1083)
- When using KVM, programming a PIT timer without a irqchip configuration, can be used to crash the kvm guest. This likely can be done only by a privileged guest user. (CVE-2011-4622)
- A KVM 32bit guest crash in 'syscall' opcode handling was fixed that could be caused by local attackers.
