Ubuntu 10.04 LTS : linux-lts-backport-oneiric vulnerabilities (USN-1688-1)

Low Nessus Plugin ID 63539


The remote Ubuntu host is missing one or more security-related patches.


Jon Howell reported a flaw in the Linux kernel's KVM (Kernel-based virtual machine) subsystem's handling of the XSAVE feature. On hosts, using qemu userspace, without the XSAVE feature an unprivileged local attacker could exploit this flaw to crash the system. (CVE-2012-4461)

A flaw was discovered in the Linux kernel's handling of script execution when module loading is enabled. A local attacker could exploit this flaw to cause a leak of kernel stack contents.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
