Description
The vulnerability allow a remote attacker to cause DoS condition or potentially execute arbitrary code on the target syste.
The weakness exists due to buffer overflow in the util-print.c:relts_print() in multiple protocol parsers (DNS, DVMRP, HSRP, IGMP, lightweight resolver protocol, PIM). A remote attacker can use a specially crafted protocol to trigger memory corruption and cause the application to crash or possibly execute arbitrary code.
Successful exploitation of the vulnerability may result system compromise.
