27 Feb 2017 — Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. Quick emulator (QEMU) en versiones anteriores a la 2.8 construido con el soporte del emulador Cirrus CLGD 54xx VGA Emulator es vulnerable a un p... • http://rhn.redhat.com/errata/RHSA-2017-0328.html • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

21 Feb 2017 — Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host.

21 Sep 2015 — The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service (infinite loop and guest crash) via unspecified vectors. La función process_tx_desc en el archivo hw/net/e1000.c en QEMU versiones anteriores a 2.4.0.1, no procesa apropiadamente los datos del descriptor de transmisión cuando se envía un paquete de red, lo que permite a atacantes causar una denegación de se... • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168077.html • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
