FreeBSD : FreeBSD -- Buffer overflow in handling of UNIX socket addresses (f56390a4-4638-11e1-9f47-00e0815b8da8)

high Nessus Plugin ID 57742

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

When a UNIX-domain socket is attached to a location using the bind(2) system call, the length of the provided path is not validated. Later, when this address was returned via other system calls, it is copied into a fixed-length buffer.

Linux uses a larger socket address structure for UNIX-domain sockets than FreeBSD, and the FreeBSD's linux emulation code did not translate UNIX-domain socket addresses into the correct size of structure.

Solution

Update the affected packages.
