| Revision Date: | 2013-06-07 | Version: | 1 | | Title: | CVE-2013-2850 on Ubuntu 16.04 LTS (xenial) - high. | | Description: | Heap-based buffer overflow in the iscsi_add_notunderstood_response function in drivers/target/iscsi/iscsi_target_parameters.c in the iSCSI target subsystem in the Linux kernel through 3.9.4 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. Heap-based buffer overflow in the iscsi_add_notunderstood_response function in drivers/target/iscsi/iscsi_target_parameters.c in the iSCSI target subsystem in the Linux kernel through 3.9.4 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. Performing discovery in a loop will Oops the remote server. Heap-based buffer overflow in the iscsi_add_notunderstood_response function in drivers/target/iscsi/iscsi_target_parameters.c in the iSCSI target subsystem in the Linux kernel through 3.9.4 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. Performing discovery in a loop will Oops the remote server. Attached is a proposed fix, and the patch I used in open-iscsi to trigger it. Thanks in advance for your cooperation in coordinating a fix for this issue, Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote unauthenticated attacker could exploit this flaw to cause a denial of service (system crash) or potentially gain administrative privileges.
