Debian: DSA-2252-1: dovecot security update
Summary
It was discovered that the message header parser in the Dovecot mail
server parsed NUL characters incorrectly, which could lead to denial
of service through malformed mail headers.
The oldstable distribution (lenny) is not affected.
For the stable distribution (squeeze), this problem has been fixed in
version 1.2.15-7.
For the unstable distribution (sid), this problem has been fixed in
version 2.0.13-1.
We recommend that you upgrade your dovecot packages.
