Detail
| 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. |

| 72156 | Exim src/dkim.c dkim_exim_verify_finish() Function DKIM-Signature Header Form... Exim is prone to a format string condition. The dkim_exim_verify_finish() function fails to properly sanitize format string specifiers (e.g., %s and %x) in the DKIM-Signature header. With a specially crafted email, a remote attacker can potentially cause arbitrary code execution. |
