Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that Exim, the default mail transport agent in Debian, uses DKIM data obtain from DNS directly in a format string, potentially allowing malicious mail senders to execute arbitrary code.
(CVE-2011-1764 )

The oldstable distribution (lenny) is not affected by this problem because it does not contain DKIM support.

Solution

Upgrade the exim4 packages.

For the stable distribution (squeeze), this problem has been fixed in version 4.72-6+squeeze1.
