This allows an attacker to spoof arbitrary SSL-based SMTP servers via a crafted server certificate issued by a legitimate Certification Authority, and to bypass intended access restrictions via a crafted client certificate issued by a legitimate Certification Authority.

For the oldstable distribution (etch), this problem has been fixed in version 8.13.8-3+etch1

For the stable distribution (lenny), this problem has been fixed in version 8.14.3-5+lenny1

For the unstable distribution (sid), this problem has been fixed in version 8.14.3-9.1, and will migrate to the testing distribution (squeeze) shortly.

We recommend that you upgrade your sendmail package.");
