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.
