There is currently very little information about this issue. More investigation/information is necessary before affected codestreams can be defined.

It was confirmed by upstream that this issue affects https://github.com/libarchive/libarchive.

https://github.com/libarchive/libarchive/commit/eb7939b24a681a04648a59cdebd386b1e9dc9237
Comment 5 Camila Camargo de Matos 2024-04-23 13:52:25 UTC 
Libarchive packages that contain the software at a version earlier than 3.6.0 seem to not be affected by this issue, as the vulnerable function, 'execute_filter_e8', was only introduced in version 3.6.0 together with the RAR filter support functionality. See [0] and [1] for more information.
