Symantec Enterprise Firewall/VPN Appliances 100, 200, and 200R running firmware before 1.63 allow remote attackers to cause a denial of service (device freeze) via a fast UDP port scan on the WAN interface.

Symantec Enterprise Firewall/VPN Appliances 100, 200, and 200R running firmware before 1.63 and Gateway Security 320, 360, and 360R running firmware before 622 uses a default read/write SNMP community string, which allows remote attackers to alter the firewall's configuration file.

Symantec Enterprise Firewall/VPN Appliances 100, 200, and 200R running firmware before 1.63 and Gateway Security 320, 360, and 360R running firmware before 622 allow remote attackers to bypass filtering and determine whether the device is running services such as tftpd, snmpd, or isakmp via a UDP port scan with a source port of UDP 53.

Dynamic VPN Configuration Protocol service (DVCP) in Watchguard Firebox firmware 5.x.x allows remote attackers to cause a denial of service (crash) via a malformed packet containing tab characters to TCP port 4110.

The FTP service in Watchguard Soho Firewall 5.0.35a allows remote attackers to gain privileges with a correct password but an incorrect user name.

Watchguard SOHO firewall before 5.0.35 allows remote attackers to cause a denial of service (crash and reboot) when SOHO forwards a packet with bad IP options.

Watchguard SOHO firewall 5.0.35 unpredictably disables certain IP restrictions for customized services that were set before the administrator upgrades to 5.0.35, which could allow remote attackers to bypass the intended access control rules.

WatchGuard SOHO FireWall 2.2.1 and earlier allows remote attackers to cause a denial of service via a large number of GET requests.

HTTP server on the WatchGuard SOHO firewall does not properly restrict access to administrative functions such as password resets or rebooting, which allows attackers to cause a denial of service or conduct unauthorized activities.

Buffer overflow in HTTP server on the WatchGuard SOHO firewall allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long GET request.
