https://notcve.org/view.php?id=CVE-2014-8106
Heap-based buffer overflow in the Cirrus VGA emulator (hw/display/cirrus_vga.c) in QEMU before 2.2.0 allows local guest users to execute arbitrary code via vectors related to blit regions. NOTE: this vulnerability exists because an incomplete fix for CVE-2007-1320. Desbordamiento de buffer basado en memoria dinámica en el emulador Cirrus VGA (hw/display/cirrus_vga.c) en QEMU anterior a 2.2.0 permite a usuarios locales invotados ejecutar código arbitrario a través de vectores relacionados con las regiones blit. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2007-1320. It was found that the Cirrus blit region checks were insufficient. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=bf25983345ca44aec3dd92c57142be45452bd38a http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=d3532a0db02296e687711b8cdc7791924efccea0 http://lists.fedoraproject.org/pipermail/package-announce/2015-April/154656.html http://lists.gnu.org/archive/html/qemu-devel/2014-12/msg00508.html http://rhn.redhat.com/errata/RHSA-2015-0349.html http://rhn.redhat.com/errata/RHSA-2015-0624.html http://rhn.redhat.com/errata/RHSA-2015-0643.html http://rhn.redhat.com&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
