mailman - programming error

A potential denial of service problem has been discovered in mailman,
the web-based GNU mailing list manager. The (failing) parsing of
messages with malformed mime multiparts sometimes caused the whole
mailing list to become inoperative.

The old stable distribution (woody) is not vulnerable to this issue.

For the stable distribution (sarge) this problem has been fixed in
version 2.1.5-8sarge2.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your mailman package.
