Comment 2 Peter Lemenkov 2026-04-12 10:47:11 UTC

The CVE IDs in this ticket appear to be malformed/garbled identifiers from an automated tool. Based on investigation, they map to the following real pjsip CVEs:

- CVE-2021-438450/438451 → CVE-2021-43845 (fixed in pjsip 2.12)
- CVE-2022-217221 → CVE-2022-21722 (fixed in pjsip 2.12)
- CVE-2022-247541/247542 → CVE-2022-24754 (fixed in pjsip 2.13)
- CVE-2022-247631/247633 → CVE-2022-24763 (fixed in pjsip 2.13)
- CVE-2022-247641 → CVE-2022-24764 (fixed in pjsip 2.13)
- CVE-2022-247931 → CVE-2022-24793 (fixed in pjsip 2.13)
- CVE-2022-247935 → CVE-2022-24793 (fixed in pjsip 2.13)

All underlying issues were addressed in pjsip 2.12/2.13, both of which shipped in Asterisk 18.x before 18.12.1. The asterisk-18.26.4 update now in EPEL 8/9 bundles pjproject 2.15.1, so all these issues are fully resolved.

Comment 3 Peter Lemenkov 2026-04-12 10:47:58 UTC

Reopening — the fix is available via the asterisk-18.26.4 update for EPEL 8/9, which bundles pjproject 2.15.1. Let Bodhi handle closure when the update goes stable.
