CVE-2011-1407

Publication date 16 May 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The DKIM implementation in Exim 4.7x before 4.76 permits matching for DKIM identities to apply to lookup items, instead of only strings, which allows remote attackers to execute arbitrary code or access a filesystem via a crafted identity.
