Vulnerability details
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code.
The weakness exists due to an error in the rpki_rtr_pdu_print function in print-rpki-rtr.c in the TCP printer. A remote attacker can supply a specially crafted header length in an RPKI-RTR Protocol Data Unit (PDU), trigger out-of-bounds read or write and cause the system crash or execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
