Description

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.

Affected configurations

• novell suse linux enterprise server 10.0 • linux linux kernel (<= 2.6.38.8) • linux linux kernel 2.6.38 • linux linux kernel 2.6.38.1 • linux linux kernel 2.6.38.2 • linux linux kernel 2.6.38.3 • linux linux kernel 2.6.38.4 • linux linux kernel 2.6.38.5 • linux linux kernel 2.6.38.6 • linux linux kernel 2.6.38.7
