Comment 1 Perry Werneck 2019-08-26 12:18:12 UTC
By the description the CVE seens to be related to the old 5.1 version of pw3270; the current version 5.2 (available in https://build.opensuse.org/package/show/X11:terminals/lib3270-5.2) does more checks on the SSL certificate.

Regarding to the security there are major changes in lib3270 planned to version 5.2 including a better way to check for certificate revogation.

Not sure if it's better submit the version 5,2 to Leap 15 or waits for the new version (it will take some time because I usually waits for the cicle of test/deploy before submit to main repos).
Comment 2 Wolfgang Frisch 2019-08-26 15:36:37 UTC
Is it feasible to apply the patch to the current version 5.1 in Leap?
That would be the best option, in my humble opinion.
Then you don't have to rush the release of pw3270-5.2.

Yes; it's feasible; the proposed patch was attached. It's not the same behavior of the latest code but, I thing, it solves the problem by showing a warning popup when the validation fails.

Not fixed in Leap 15.1 yet.
Comment 6 Alexanre Werneck 2020-01-17 11:58:39 UTC
What's the process to submit the patch or, better, the new version from factory as an update for Leap 15.1?

I'm sorry for the very late response. The bug had been lost in the ether.
All openSUSE packages of pw3270 have long been fixed.
