TITLE

Gauntlet Firewall Decline service vulnerability

Trust: 0.6

sources: CNNVD: CNNVD-199907-039

DESCRIPTION

Denial of service in Gauntlet Firewall via a malformed ICMP packet. The vulnerability occurs because Gauntlet Firewall cannot handle a condition where an ICMP Protocol Problem packet's (ICMP_PARAMPROB) encapsulated IP packet has a random protocol field and certain IP options set. The packet structure looks like this: Begin Packet ------------------------------------------ [NORMAL IP HEADER] [ICMP PARAMPROB HEADER] -- encapsulated ip packet -- [IP HEADER] (important fields in ip header) ip_p = 98 (let's specify a protocol that doesn't exist) ip_hl = 0xf (stuff options) ------------------------------------------ End Packet An attacker would do the following: Construct the [ip-icmp-ip] packet using a raw socket (SOCK_RAW) with the fields set accordingly, destination set to any machine behind the firewall. Send the packet(s). The number of packets that need to be sent depends on the platform (ie Sol on a Sparc vs BSDI). The consequence of this vulnerability being exploited is the target Gauntlet 5.0 firewall being remotely locked up. It should be expected that an attacker would send packets with spoofed source addresses in the ip header making it difficult to trace
