tcpdump rsvp_print function denial of service
| tcpdump-rsvpprint-dos (20291) |  Low Risk |
Description:
The tcpdump utility is vulnerable to a denial of service attack caused by a vulnerability in the rsvp_print() function. A remote attacker could send a specially-crafted RSVP packet to cause tcpdump to enter into an infinite loop and stop responding.
