Detailsinfo

A vulnerability, which was classified as problematic, has been found in QEMU (Virtualization Software) (version now known). This issue affects some unknown processing of the component IDE Subsystem. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was shared 08/12/2015 by Kevin Wolf with Red Hat (Website). The advisory is shared at xenbits.xen.org. The identification of this vulnerability is CVE-2015-5154 since 07/01/2015. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 06/09/2022).
