The Decomposer component in multiple Symantec products allows remote attackers to cause a denial of service (infinite loop) via a certain value in the PACKSIZE field of a RAR archive file header.

Heap-based buffer overflow in the Decomposer component in multiple Symantec products allows remote attackers to execute arbitrary code via multiple crafted CAB archives.

Buffer overflow in the Internet Key Exchange version 1 (IKEv1) implementation in Symantec Dynamic VPN Services, as used in Enterprise Firewall, Gateway Security, and Firewall /VPN Appliance products, allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1.

Unknown vulnerability in the DNSd proxy, as used in Symantec Gateway Security 5400 2.x and 5300 1.x, Enterprise Firewall 7.0.x and 8.x, and VelociRaptor 1100/1200/1300 1.5, allows remote attackers to poison the DNS cache and redirect users to malicious sites.
