Fix for this issue can be found here https://github.com/OpenSC/OpenSC/pull/2948
I will backport it into our codestreams

I'm on it.

Fix for this is already present in 0.25.0, so Factory is ok. Will backport to SLE.

Comment 10 Martin Schreiner 2024-05-15 13:46:01 UTC

SLE-11 is out of support, so that request won't be submitted.

Only SLE-15:Update and SLE-15-SP1:Update are still to be released, but their SRs have already been submitted on IBS:

SLE-15-SP1
https://build.suse.de/request/show/329349

SLE-15
https://build.suse.de/request/show/329348

I'm reassigning this to the security team

Comment 11 Martin Schreiner 2024-05-15 13:49:33 UTC

Just an extra piece of info, regarding opensc no longer being supported on SLE-11,  you can double-check that using https://smelt.suse.de, just search for 'opensc', I'm unable to find a direct link.
