This update for qemu fixes the following issues:

  • Remove a backslash '' escape character from 80-qemu-ga.rules (bsc#1153358) Unlike sles 15 or newer guests, The udev rule file of qemu guest agent in sles 12 sp4 or newer guest only needs one escape character.

  • Fix use-after-free in slirp (CVE-2018-20126 bsc#1119991)

  • Fix potential DOS in lsi scsi controller emulation (CVE-2019-12068 bsc#1146873)

  • Expose taa-no 'feature', indicating CPU does not have the TSX Async Abort vulnerability. (CVE-2019-11135 bsc#1152506)

  • Expose pschange-mc-no 'feature', indicating CPU does not have the page size change machine check vulnerability (CVE-2018-12207 bsc#1155812)

  • Patch queue updated from https://gitlab.suse.de/virtualization/qemu.git SLE12-SP4

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access.

Описание

In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8~deb10u1, 1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12 (fixed), when executing script in lsi_execute_script(), the LSI scsi adapter emulator advances 's->dsp' index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well.
