CVE-2013-2850

CVSS v2.0

7.9

High

VectorAV:A/AC:M/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel versions through 3.9.4
Description A heap-based buffer overflow in the iscsi add notunderstood response function in the iSCSI target subsystem allows remote attackers to cause a denial of service (memory corruption and OOPS) or possibly execute arbitrary code via a long key that is not properly handled during construction of an error-response packet. A reproduction case requires patching open-iscsi to send overly large keys, and performing discovery in a loop can cause the remote server to crash.
Recommendations For Linux kernel versions through 3.9.4, update to a version later than 3.9.4 to resolve the issue. As a temporary workaround, consider restricting access to the iscsi add notunderstood response function to minimize the risk of exploitation. Avoid using long keys in the iSCSI target subsystem until the issue is resolved.
