Description Karol Babioch 2018-10-01 07:31:28 UTC

CVE-2018-17582

tcpreplay v4.3.0 contains a heap-based buffer over-read. The get_next_packet()
function in the send_packets.c file uses the memcpy() function unsafely to copy
sequences from the source buffer pktdata to the destination
(*prev_packet)->pktdata. This will result in a Denial of Service (DoS) and
potentially Information Exposure when the application attempts to process a
file.

Comment 1 Karol Babioch 2018-10-01 07:44:19 UTC

Since 4.3.0 is not yet released, this is not a problem for us.

Comment 2 Michal Kubeček 2018-10-03 08:12:02 UTC

Reopening. While the CVE talks about version 4.3.0 Beta 1, the code in question
is much older and works the same way in version 4.2.6 (Tumbleweed, 15.0) and
4.1.2 (42.3).

Comment 3 Tomáš Chvátal 2019-07-11 11:34:49 UTC

This is automated batch bugzilla cleanup.

The openSUSE 42.3 changed to end-of-life (EOL [1]) status. As such
it is no longer maintained, which means that it will not receive any
further security or bug fix updates.
As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
openSUSE (At this moment openSUSE Leap 15.1, 15.0 and Tumbleweed) please
feel free to reopen this bug against that version (!you must update the
"Version" component in the bug fields, do not just reopen please), or
alternatively create a new ticket.

Thank you for reporting this bug and we are sorry it could not be fixed
during the lifetime of the release.

15.0 and 15.1 unfixed
