CVE-2015-5154

Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands...

CVE-2015-5154

CVE-2015-5154 is a heap-based buffer overflow in QEMU’s IDE subsystem (ATAPI handling). A privileged guest with a CDROM drive enabled could potentially execute arbitrary host code via crafted ATAPI I/O. Public docs specify this as a host-attack surface when CD-ROM access is present; Debian securi...
