Detail
| It was discovered that sendmail, a Mail Transport Agent, does not properly handle a '\0' character in a Common Name (CN) field of an X.509 certificate. 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. |
