WatchGuard

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.

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.

SMTP proxy in WatchGuard Firebox (2500 and 4500) 4.5 and 4.6 allows a remote attacker to bypass firewall filtering via a base64 MIME encoded email attachment whose boundary name ends in two dashes.

Watchguard Firebox II prior to 4.6 allows a remote attacker to create a denial of service in the kernel via a large stream (>10,000) of malformed ICMP or TCP packets.

Watchguard Firebox II allows remote attackers to cause a denial of service by establishing multiple connections and sending malformed PPTP packets.

Watchguard Firebox II firewall allows users with read-only access to gain read-write access, and administrative privileges, by accessing a file that contains hashed passphrases, and using the hashes during authentication.

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.

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.

WatchGuard SOHO firewall allows remote attackers to cause a denial of service via a flood of fragmented IP packets, which causes the firewall to drop connections and stop forwarding packets.

WatchGuard Firebox II allows remote attackers to cause a denial of service by flooding the Firebox with a large number of FTP or SMTP requests, which disables proxy handling.

Watchguard Firebox II allows remote attackers to cause a denial of service by sending a malformed URL to the authentication service on port 4100.
