Package        : yardradius
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-0987
Debian Bug     : 278384

Max Vozeler noticed that yardradius, the YARD radius authentication
and accounting server, contained a stack overflow similar to the one
from radiusd which is referenced as CAN-2001-0534.  This could lead to
the execution of arbitrary code as root.

For the stable distribution (woody) this problem has been fixed in
version 1.0.20-2woody1.

For the unstable distribution (sid) this problem has been fixed in
version 1.0.20-15.

We recommend that you upgrade your yardradius package immediately.
