CWE-ID: CWE-20

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in the functions pi_next_lrcp(), pi_next_rlcp(), pi_next_rpcl(), pi_next_pcrl(), pi_next_rpcl(), and pi_next_cprl() in openmj2/pi.c.
