Detailsinfo

A vulnerability has been found in QEMU 0.15.0/0.15.1/1.0 (Virtualization Software) and classified as critical. Affected by this vulnerability is the function ccid_card_vscard_handle_message. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in the ccid_card_vscard_handle_message function in hw/ccid-card-passthru.c in QEMU before 0.15.2 and 1.x before 1.0-rc4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VSC_ATR message.

The weakness was released 02/26/2014 by Petr Matousek as confirmed git commit (GIT Repository). It is possible to read the advisory at git.qemu.org. This vulnerability is known as CVE-2011-4111 since 10/18/2011. The exploitation appears to be difficult. The attack needs to approached within the local network. The exploitation doesn't need any form of authentication. Technical details of the vulnerability are known, but there is no available exploit.
