Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.04 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: Sasha Levin discovered a flaw in the permission checking for device assignments requested via the kvm ioctl in the Linux kernel. A local user could use this flaw to crash the system causing a denial of service. (CVE-2011-4347) Stephan Bärwolf discovered a flaw in the KVM (kernel-based virtual machine) subsystem of the Linux kernel. A local unprivileged user can crash use this flaw to crash VMs causing a deny of service. (CVE-2012-0045) H. Peter Anvin reported a flaw in the Linux kernel that could crash the system. A local user could exploit this flaw to crash the system. (CVE-2012-1097) A flaw was discovered in the Linux kernel's cgroups subset. A local attacker could use this flaw to crash the system. (CVE-2012-1146) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.04: After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.

| Title: | DSA-2443-1 linux-2.6 -- privilege escalation/denial of service | ||
| Description: | Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-4307 Nageswara R Sastry reported an issue in the ext4 filesystem. Local users with the privileges to mount a filesystem can cause a denial of service by providing a s_log_groups_per_flex value greater than 31. CVE-2011-1833 Vasiliy Kulikov of Openwall and Dan Rosenberg discovered an information leak in the eCryptfs filesystem. Local users were able to mount arbitrary directories. CVE-2011-4347 Sasha Levin reported an issue in the device assignment functionality in KVM. Local users with permission to access /dev/kvm could assign unused pci devices to a guest and cause a denial of service. CVE-2012-0045 Stephan Barwolf reported an issue in KVM. Local users in a 32-bit guest running on a 64-bit system can crash the guest with a syscall instruction. CVE-2012-1090 CAI Qian reported an issue in the CIFS filesystem. A reference count leak can occur during the lookup of special files, resulting in a denial of service on umount. CVE-2012-1097 H. Peter Anvin reported an issue in the regset infrastructure. Local users can cause a denial of service by triggering the write methods of readonly regsets. | ||
