Juniper Junos before 10.4S14, 11.4 before 11.4R5-S2, 12.1R before 12.1R3, 12.1X44 before 12.1X44-D20, and 12.1X45 before 12.1X45-D15 on SRX Series services gateways, when a plugin using TCP proxy is configured, allows remote attackers to cause a denial of service (flow daemon crash) via an unspecified sequence of TCP packets.

Unspecified vulnerability in Juniper JUNOS 7.3 through 8.4 allows remote attackers to cause a denial of service (crash) via malformed BGP packets, possibly BGP UPDATE packets that trigger session flapping.

Memory leak in Juniper JUNOS 6.4 through 8.0, built before May 10, 2006, allows remote attackers to cause a denial of service (kernel packet memory consumption and crash) via crafted IPv6 packets whose buffers are not released after they are processed.
