Description Andrej Nemec 2016-04-22 07:47:27 UTC

A vulnerability was found in mutt. The builtin pager would truncate the attachment output after null byte. This might give the attacker the opportunity to provide malicious input, which won't be seen by the victim.

Original bug report (with reproducer):

Created mutt tracking bugs for this issue:

Affects: fedora-all [bug 1329528]

Comment 2 Dhiru Kholia 2016-06-01 11:01:08 UTC

The user might get confused by the partial rendering of the attachment but the user needs to take further steps (like running arbitrary attachments) to get compromised.

Comment 3 Honza Horak 2016-10-05 13:04:26 UTC

So we can close bug #1329528 as well, right?

Comment 4 Fabio Alessandro Locati 2016-10-05 13:45:34 UTC

@Honza, I think that we should do it
