Description Pedro Sampaio 2019-10-10 17:15:04 UTC

tcpdump before 4.9.3 mishandles the printing of SMB data (issue 2 of 2).

Comment 1 Pedro Sampaio 2019-10-11 00:03:32 UTC

Created tcpdump tracking bugs for this issue:

Affects: fedora-all [bug 1760626]

Comment 2 Riccardo Schirone 2020-02-11 08:55:56 UTC

It seems there is no real fix for this issue and no details about it. The SMB printer has been disabled in tcpdump 4.9.3 (as it can be seen at https://github.com/the-tcpdump-group/tcpdump/blob/tcpdump-4.9/CHANGES#L17 and https://github.com/the-tcpdump-group/tcpdump/commit/eb585ee78413978df836dd6dda42914b53981d75).

Comment 3 Riccardo Schirone 2020-02-11 08:56:36 UTC

The score for this flaw is very high as there are no details about it and upstream was not able to provide more information on its nature. We could not determine the real impact of this security issue.
