SuSE 11.2 Security Update : Xen (SAT Patch Number 7492)

high Nessus Plugin ID 65797

Language:

Synopsis

The remote SuSE 11 host is missing one or more security updates.

Description

XEN has been updated to fix various bugs and security issues :

- (XSA 36) To avoid an erratum in early hardware, the Xen AMD IOMMU code by default choose to use a single interrupt remapping table for the whole system. This sharing implied that any guest with a passed through PCI device that is bus mastering capable can inject interrupts into other guests, including domain 0. This has been disabled for AMD chipsets not capable of it.
(CVE-2013-0153)

- qemu: The e1000 had overflows under some conditions, potentially corrupting memory. (CVE-2012-6075)

- (XSA 37) Hypervisor crash due to incorrect ASSERT (debug build only). (CVE-2013-0154)

- (XSA-33) A VT-d interrupt remapping source validation flaw was fixed. Also the following bugs have been fixed :. (CVE-2012-5634)

- xen hot plug attach/detach fails. (bnc#805094)

- domain locking can prevent a live migration from completing. (bnc#802690)

- no way to control live migrations. (bnc#797014)

- fix logic error in stdiostream_progress

- restore logging in xc_save
