CVE-2011-4913
Estado: ModificadaAlta (7.8)—
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.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
- Puntuación base: 7.8
