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.
We apologize for the inconvenience.
Original advisory details:
Brad Spengler discovered a flaw in the Linux kernelβs uname system call. An
unprivileged user could exploit this flaw to read kernel stack memory.
(CVE-2012-0957)
Jon Howell reported a flaw in the Linux kernelβs KVM (Kernel-based virtual
machine) subsystemβs 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)
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. (CVE-2012-4508)
A flaw was discovered in the Linux kernelβs handling of script execution
when module loading is enabled. A local attacker could exploit this flaw to
cause a leak of kernel stack contents. (CVE-2012-4530)
Rodrigo Freire discovered a flaw in the Linux kernelβs TCP illinois
congestion control algorithm. A local attacker could use this to cause a
denial of service. (CVE-2012-4565)
A flaw was discovered in the Linux kernelβs handling of new hot-plugged
memory. An unprivileged local user could exploit this flaw to cause a
denial of service by crashing the system. (CVE-2012-5517)
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. (CVE-2012-5532)
