Mutt IMAP namespace buffer overflow A buffer overflow flaw was found in the way mutt processes an overly long namespace from a malicious imap server. In order to exploit this flaw a user would have to connect to a malicious IMAP server. http://secunia.com/advisories/20810
mutt-1.4.2.1-5.fc4 has been pushed for fc4, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
