CVE-2011-4913Date: (C)2012-06-21   (M)2024-01-04


The rose_parse_ccitt function in net/rose/rose_subr.c in the Linux kernel before 2.6.39 does not validate the FAC_CCITT_DEST_NSAP and FAC_CCITT_SRC_NSAP fields, which allows remote attackers to (1) cause a denial of service (integer underflow, heap memory corruption, and panic) via a small length value in data sent to a ROSE socket, or (2) conduct stack-based buffer overflow attacks via a large length value in data sent to a ROSE socket.
