Ubuntu Security Notice USN-1704-2
Posted Feb 2, 2013
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1704-2 - USN-1704-1 fixed vulnerabilities in the Linux kernel. Due to an unrelated regression inotify/fanotify stopped working after upgrading. This update fixes the problem. Brad Spengler discovered a flaw in the Linux kernel's uname system call. An unprivileged user could exploit this flaw to read kernel stack memory. 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. Dmitry Monakhov reported a race condition flaw the Linux ext4 filesystem that can expose stale data. An unprivileged user could exploit this flaw to cause an information leak. 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. Rodrigo Freire discovered a flaw in the Linux kernel's TCP illinois congestion control algorithm. A local attacker could use this to cause a denial of service. A flaw was discovered in the Linux kernel's handling of new hot-plugged memory. An unprivileged local user could exploit this flaw to cause a denial of service by crashing the system. Florian Weimer discovered that hypervkvpd, which is distributed in the Linux kernel, was not correctly validating source addresses of netlink packets. An untrusted local user can cause a denial of service by causing hypervkvpd to exit. Various other issues were also addressed.

Red Hat Security Advisory 2012-1491-01
Posted Dec 4, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-1491-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way Netlink messages without SCM_CREDENTIALS data set were handled. When not explicitly set, the data was sent but with all values set to 0, including the process ID and user ID, causing the Netlink message to appear as if it were sent with root privileges. A local, unprivileged user could use this flaw to send spoofed Netlink messages to an application, possibly resulting in the application performing privileged operations if it relied on SCM_CREDENTIALS data for the authentication of Netlink messages.
