Package        : netkit-rwho
Vulnerability  : missing input validation
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-1180

"Vlad902" discovered a vulnerability in the rwhod program that can be
used to crash the listening process.  The broadcasting one is
unaffected.  This vulnerability only affects little endian
architectures (i.e. on Debian: alpha, arm, alpha, ia64, i386, mipsel
and s390).

For the stable distribution (woody) this problem has been fixed in
version 0.17-4woody2.

For the unstable distribution (sid) this problem has been fixed in
version 0.17-8.

We recommend that you upgrade your rwhod package.
