FreeBSD 7.3 to 9.0-RC1 privilege escalation/denial of service

high Nessus Plugin ID 110559

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Buffer overflow in the 'Linux emulation' support in FreeBSD kernel allows local users to cause a denial of service (panic) and possibly execute arbitrary code by calling the bind system call with a long path for a UNIX-domain socket, which is not properly handled when the address is used by other unspecified system calls.

Solution

Upgrade your vulnerable system to 7-STABLE or 8-STABLE, or to the RELENG_8_2, RELENG_8_1, RELENG_7_4, or RELENG_7_3 security branch dated after the correction date.
