Description

Xen was updated to 4.3.4 to fix multiple vulnerabities and non-security bugs.

The following vulnerabilities were fixed :

  • Long latency MMIO mapping operations are not preemptible (XSA-125 CVE-2015-2752 bnc#922705)

  • Unmediated PCI command register access in qemu (XSA-126 CVE-2015-2756 bnc#922706)

  • Hypervisor memory corruption due to x86 emulator flaw (bnc#919464 CVE-2015-2151 XSA-123)

  • Information leak through version information hypercall (bnc#918998 CVE-2015-2045 XSA-122)

  • Information leak via internal x86 system device emulation (bnc#918995 (CVE-2015-2044 XSA-121)

  • HVM qemu unexpectedly enabling emulated VGA graphics backends (bnc#919663 CVE-2015-2152 XSA-119)

  • information leakage when guest sets high resolution (bnc#895528 CVE-2014-3615)

The following non-security bugs were fixed :

  • L3: XEN blktap device intermittently fails to connect (bnc#919098)

  • Problems with detecting free loop devices on Xen guest startup (bnc#903680)

  • xentop reports 'Found interface vif101.0 but domain 101 does not exist.' (bnc#861318)

  • Intel ixgbe driver assigns rx/tx queues per core resulting in irq problems on servers with a large amount of CPU cores (bnc#901488)

  • SLES11 SP3 Xen VT-d igb NIC doesn't work (bnc#910254)
