Vulnerability identifier: #VU25510
Vulnerability risk: Medium
Exploitation vector: Network
Exploit availability: No
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a boundary error in the way the iSCSI Block driver handles a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an "iscsi_co_block_status()" routine. A remote authenticated attacker can trigger heap-based buffer overflow and cause a denial of service condition or potentially execute arbitrary code with privileges of the QEMU process on the host.
