Package : exim-tls
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-0021
Debian Bug : 289046

Philip Hazel announced a buffer overflow in the host_aton function in exim-tls, the SSL-enabled version of the default mail-tranport-agent in Debian, which can lead to the execution of arbitrary code via an illegal IPv6 address.

For the stable distribution (woody) this problem has been fixed in version 3.35-3woody3.

In the unstable distribution (sid) this package does not exist anymore.

We recommend that you upgrade your exim-tls package.
