TITLE:
Mutt IMAP Namespace Buffer Overflow Vulnerability
SECUNIA ADVISORY ID:
SA20810
VERIFY ADVISORY:
http://secunia.com/advisories/20810/
CRITICAL:
Moderately critical
IMPACT:
DoS, System access
WHERE:
>From remote
SOFTWARE:
Mutt 1.4.x
http://secunia.com/product/1305/
DESCRIPTION:
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 1.4.2.1. Prior
versions may also be affected.
SOLUTION:
The vulnerability has been fixed in the CVS repositories.
