GNU libc, which is derived from the SunRPC library. This bug could be
exploited to gain unauthorized root access to software linking to this
code. The packages below also fix integer overflows in the malloc
code. They also contain a fix from Andreas Schwab to reduce linebuflen
in parallel to bumping up the buffer pointer in the NSS DNS code."
