Debian: l2tpd Buffer overflow vulnerability
Summary
Thomas Walpuski reported a buffer overflow in l2tpd, an implementation
of the layer 2 tunneling protocol, whereby a remote attacker could
potentially cause arbitrary code to be executed by transmitting a
specially crafted packet. The exploitability of this vulnerability
has not been verified.
For the current stable distribution (woody), this problem has been
fixed in version 0.67-1.2.
For the unstable distribution (sid), this problem has been fixed in
version 0.70-pre20031121-2.
We recommend that you update your l2tpd package.
