As a result, unprivileged local users were able to inject commands into running fep sessions of other users. The upstream fix simply removes abstract namespace support, using a restricted directory to host the UNIX domain socket instead: https://github.com/ueno/libfep/commit/293d9d3f Abstract namespace support was introduced in this commit: https://github.com/ueno/libfep/commit/5a170323 This means that versions from 0.0.5 to 0.0.9 (inclusive) are vulnerable, and 0.1.0 has the fix. -- Florian Weimer / Red Hat Product Security Team
