Security update for qemu

This update fixes the following security issues:

  • Enforce receive packet size, thus eliminating buffer overflow and potential security issue. (bsc#957162 CVE-2015-7512)
  • Infinite loop in processing command block list. CVE-2015-8345 (bsc#956829):

This update also fixes a non-security bug:

  • Due to space restrictions in limited bios data areas, don't create mptable if vcpu count is 'high' (ie more than ~19). (bsc#954864) (No supported guests are negatively impacted by this change, which is taken from upstream seabios)

This update was imported from the SUSE:SLE-12-SP1:Update update project.

Описание

Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet.

The eepro100 emulator in QEMU qemu-kvm blank allows local guest users to cause a denial of service (application crash and infinite loop) via vectors involving the command block list.
