The vulnerability is caused due to a boundary error in the SHA2 implementation and can be exploited to cause a buffer overflow with 4 or 8 constant bytes. NOTE: This results in a heap-based buffer overflow in the libssh library and in a stack-based buffer overflow in pkg_install. SOLUTION: Fixed in the CVS repository. See vendor advisory for details. PROVIDED AND/OR DISCOVERED BY: The vendor credits Joerg Sonnenberger.
