F5 Networks BIG-IP : Linux SACK Slowness vulnerability (K26618426)

Jonathan Looney discovered that the TCP retransmission queue implementation in tcpfragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment SACK sequences. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel...

F5 Networks BIG-IP : Excess resource consumption due to low MSS values vulnerability (K35421172)

Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kerne...

The vulnerability of the microprogrammed input/output module Moxa ioLogik 2542-HSPA and the Moxa Ioxpress Configuration Utility, related to uncontrolled resource consumption, allows a intruder to cause service failures.

The vulnerability of the microprogrammed input/output module Moxa ioLogik 2542-HSPA and the Moxa Ioxpress Configuration Utility is related to an uncontrolled resource consumption. Exploiting this vulnerability can allow a malicious actor to cause service failures by using specially crafted packag...
