Security update for qemu

This update for qemu fixes the following issues:

  • CVE-2020-7039: Fixed a heap buffer overflow in tcp_emu() routine while emulating IRC and other protocols (bsc#1161066).
  • CVE-2019-15034: Fixed a buffer overflow in hw/display/bochs-display.c due to improper PCI config space allocation (bsc#1166379).
  • CVE-2020-1711: Fixed an out of bounds heap buffer access iscsi_co_block_status() routine which could have allowed a remote denial of service or arbitrary code with privileges of the QEMU process on the host (bsc#1166240).
  • CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() routine while emulating the identification protocol and copying message data to a socket buffer (bsc#1123156).
  • CVE-2020-8608: Fixed a heap buffer overflow in tcp_emu() routine while emulating IRC and other protocols (bsc#1163018).
  • CVE-2019-20382: Fixed a memory leak in the VNC display driver which could have led to exhaustion of the host memory leading to a potential Denial of service (bsc#1165776).
  • Fixed a live migration error (bsc#1154790).
  • Fixed an issue where migrating VMs on KVM gets missing features:ospke error (bsc#1162729).

hw/display/bochs-display.c in QEMU 4.0.0 does not ensure a sufficient PCI config space allocation, leading to a buffer overflow involving the PCIe extended config space.

Описание

QEMU 4.1.0 has a memory leak in zrle_compress_data in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd.

Описание

An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host.

Описание

tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC. This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code.

Описание

In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c misuses snprintf return values, leading to a buffer overflow in later code.
