Hello shuitao!
was this reported upstream?  If not, can you please share this problem also with them?


Thank you!

Comment 2 Henri Salo 2018-12-29 03:27:49 UTC
Reported to upstream https://github.com/cacalabs/libcaca/issues/36

How do I correctly add CVEs to this Bugzilla?

Comment 4 Leonardo Taccari 2018-12-29 14:18:05 UTC
Thank you very much Henri!

(Unfortunately I do not know how to add the corresponding CVE IDs to the bug report.)

Comment 5 Leonardo Taccari 2019-01-01 01:08:10 UTC
Hello Henri,
at least on other ids I have seen that CVEs are added by populating `Alias' field.

E.g. CVE-2018-14653:

 <https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14653>

...AKA Bug 1633431:

 <https://bugzilla.redhat.com/show_bug.cgi?id=1633431>

Comment 6 Henri Salo 2019-01-03 00:34:21 UTC
I don't think I'm able to add those with my account. These issues and one new one reported by me are fixed in upstream.
