Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

libosmocore through 1.14.1 contains a buffer overflow in osmo_iuup_compute_payload_crc() in src/gsm/iuup.c. This allows a remote attacker to cause a denial of service.
