CVE-2013-2850: Linux Kernel

High severity, CVSS 7.9. EPSS: 7.3% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 3.1, before 3.2.47 (fixed in 3.2.47); from 3.3, before 3.4.48 (fixed in 3.4.48); from 3.5, before 3.9.5 (fixed in 3.9.5)
