CVE-2011-4913
Published: 04 January 2012
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.
From the Ubuntu security team
Dan Rosenberg discovered flaws in the linux Rose (X.25 PLP) layer used by amateur radio. A local user or a remote user on an X.25 network could exploit these flaws to execute arbitrary code as root.
