DEBIAN-CVE-2013-6885

The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between locked instructions and write-combined memory types, which allows local users to cause a denial of service system hang via a crafted application, aka the errata 793 issue...

Name of the Vulnerable Software and Affected Versions: AMD processors versions 16h 00h through 0Fh Description: The issue arises from the microcode's improper handling of the interaction between locked instructions and write-combined memory types. This allows local users to cause a denial of...

PV guest host Denial of Service

ISSUE DESCRIPTION A Xen user has discovered that some older AMD CPUs can be made to lock up due to AMD processor erratum 121. This issue was discovered during testing of the fix for XSA-7 CVE-2012-0217. Although the two issues are unrelated the situations which can trigger them may overlap...

DEBIAN-CVE-2012-2934

Xen 4.0, and 4.1, when running a 64-bit PV guest on "older" AMD CPUs, does not properly protect against a certain AMD processor bug, which allows local guest OS users to cause a denial of service host hang via sequential execution of instructions across a non-canonical boundary, a different...

kernel: denial of service due to AMD Erratum #121

Xen 4.0, and 4.1, when running a 64-bit PV guest on "older" AMD CPUs, does not properly protect against a certain AMD processor bug, which allows local guest OS users to cause a denial of service host hang via sequential execution of instructions across a non-canonical boundary, a different...

security flaw

The Linux kernel before 2.6.16.9 and the FreeBSD kernel, when running on AMD64 and other 7th and 8th generation AuthenticAMD processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one process to determine portions of the stat...

security flaw

Unknown vulnerability in the Linux kernel before 2.4.23, on the AMD AMD64 and Intel EM64T architectures, associated with "setting up TSS limits," allows local users to cause a denial of service crash and possibly execute arbitrary code...
