AIX 5.3 TL 7 : libc (IZ50517)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote AIX host is missing a security patch.

Description :

There is a race condition in the MALLOCDEBUG debugging component of
the malloc subsystem in the library libc.a. A local user can exploit
this race condition when executing setuid root programs and thereby
overwrite any file in the system.

The successful exploitation of this vulnerability allows a local user
to overwrite arbitrary files and execute arbitrary code as the root
user.

The following libraries are vulnerable :

/usr/ccs/lib/libc.a /usr/ccs/lib/libp/libc.a.
