Description
A flaw was found in the ISCSI target code in the Linux kernel. The flaw allows an unauthenticated, remote attacker to cause a stack buffer overflow of 17 bytes of the stack. Depending on how the kernel was compiled (e.g. compiler, compile flags, and hardware architecture), the attack may lead to a system crash or access to data exported by an iSCSI target. Privilege escalation cannot be ruled out. The highest threat from this vulnerability is to system availability.
