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
