Andy Adamson discovered a flaw in the Linux kernel's NFSv4 implementation. A remote NFS server (attacker) could exploit this flaw to cause a denial of service. (CVE-2011-4131)

A flaw was found in the Linux kernel's KVM (Kernel Virtual Machine) virtual cpu setup. An unprivileged local user could exploit this flaw to crash the system leading to a denial of service. (CVE-2012-1601)

A flaw was discovered in the Linux kernel's KVM (kernel virtual machine). An administrative user in the guest OS could leverage this flaw to cause a denial of service in the host OS. (CVE-2012-2121)

Steve Grubb reported a flaw with Linux fscaps (file system base capabilities) when used to increase the permissions of a process. For application on which fscaps are in use a local attacker can disable address space randomization to make attacking the process with raised privileges easier. (CVE-2012-2123)

Schacher Raindel discovered a flaw in the Linux kernel's memory handling when hugetlb is enabled. An unprivileged local attacker could exploit this flaw to cause a denial of service and potentially gain higher privileges. (CVE-2012-2133).

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.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:0743 advisory.

  - kernel: thp:__split_huge_page() mapcount != page_mapcount BUG_ON() (CVE-2012-1179)

  - kernel: macvtap: zerocopy: vector length is not validated before pinning user pages (CVE-2012-2119)

  - kvm: device assignment page leak (CVE-2012-2121)

  - kernel: fcaps: clear the same personality flags as suid when fcaps are used (CVE-2012-2123)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Fixes CVEs :

CVE-2012-2123 CVE-2012-2121 CVE-2012-2119

Also fixes a boot regression on some Dell machines Linux 3.3.2

There was a regression at the DVB core, affecting applications that require the DVB status before having a lock. In order to allow a broader test (including my environment).

All new patches from the upstream media tree up to Apr, 10 got backported plus the fix patches, in order to have, among other things, the az6007 and af9035 drivers backported.

Various bugfixes.

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

A flaw was discovered in the Linux kernel's KVM (kernel virtual machine). An administrative user in the guest OS could leverage this flaw to cause a denial of service in the host OS. (CVE-2012-2121)

Multiple integer overflow flaws where discovered in the Alchemy LCD frame- buffer drivers in the Linux kernel. An unprivileged local user could exploit this flaw to gain administrative privileges.
(CVE-2013-4511).

Ben Hutchings reported a flaw in the Linux kernel with some network drivers that support TSO (TCP segment offload). A local or peer user could exploit this flaw to to cause a denial of service.
(CVE-2012-3412)

Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel implementation of RDS sockets. A local unprivileged user could potentially use this flaw to read privileged information from the kernel. (CVE-2012-3430)

A flaw was discovered in the madvise feature of the Linux kernel's memory subsystem. An unprivileged local use could exploit the flaw to cause a denial of service (crash the system). (CVE-2012-3511)
