Memory leak in Huawei S5300EI, S5300SI, S5310HI, S6300EI/ S2350EI, and S5300LI Campus series switches with software V200R001C00 before V200R001SPH018, V200R002C00 before V200R003SPH011, and V200R003C00 before V200R003SPH011; S9300, S7700, and S9700 Campus series switches with software V200R001C00 before V200R001SPH023, V200R002C00 before V200R003SPH011, and V200R003C00 before V200R003SPH011; and S2300 and S3300 Campus series switches with software V100R006C05 before V100R006SPH022 allows remote attackers to cause a denial of service (memory consumption and reboot) via a large number of ICMPv6 packets.

Huawei Quidway S9700, S5700, S5300, S9300, and S7700 switches with software before V200R003SPH012 allow remote attackers to cause a denial of service (switch restart) via crafted traffic.

The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic that occasionally relies on keys affected by the Invariance Weakness, and then using a brute-force approach involving LSB values, aka the "Bar Mitzvah" issue.
