TAKAHASHI Tamotsu has reported a vulnerability in Mutt, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a user's system.
The vulnerability is caused due to a boundary error within the "browse_get_namespace()" function in browse.c. This can be exploited to cause a stack-based buffer overflow when processing an overly long namespace from the IMAP server.
Successful exploitation crashes the application and may allow arbitrary code execution, but requires that the user connects to a malicious IMAP server.
The vulnerability has been reported in version 220.127.116.11. Prior versions may also be affected.
