- Security database references:
- In the Debian bugtracking system: Bug 624670.

- More information:
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.
For the stable distribution (squeeze), this problem has been fixed in version 4.72-6+squeeze1.
For the unstable distribution (sid), this problem has been fixed in version 4.75-3.
We recommend that you upgrade your exim4 packages.
