Description

It was discovered that there was a heap-based buffer overflow in procmail, a tool used to sort incoming mail into various directories and filter out spam messages.

For Debian 7 'Wheezy', this issue has been fixed in procmail version 3.22-20+deb7u2.

We recommend that you upgrade your procmail packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
