CVE-2019-20096

A flaw was found in the Linux kernel’s implementation of the Datagram Congestion Control Protocol DCCP. A local attacker with access to the system can create DCCP sockets to cause a memory leak and repeat this operation to exhaust all memory and panic the system. Mitigation As the DCCP module wil...

Akamai Improves Global Delivery Performance

As part of Akamai's ongoing investments in improving delivery performance, last month we completed the worldwide deployment of the Bottleneck Bandwidth and RTT BBR TCP congestion control algorithm across our Edge Platform. The BBR algorithm is designed to help improve the reliability and resilien...

Do High Vanity Bitrates Choke Your Live OTT Service Out of the Gate?

Studies show that video consumption demand is growing faster than capacity. While capacity overhead does exist, current trends suggest that we'll see more bottlenecking on last-hop connectivity, especially with regionally targeted content. By pushing "vanity bitrates" -- those topmost speeds that...

Denial Of Service

The kernel packages is vulnerable to use-after-free flaw. Linux kernel's Datagram Congestion Control Protocol DCCP implementation has a flaw in freeing SKB socket buffer resources for a DCCPPKTREQUEST packet when the IPV6RECVPKTINFO option is set on the socket, allowing a local user with little...

Denial Of Service (DoS)

The kernel-rt package is vulnerable to denial of serviceDoS. The attack exists because of a use-after-free flaw in the way the Linux kernel's Datagram Congestion Control Protocol DCCP implementation freed SKB socket buffer resources for a DCCPPKTREQUEST packet when the IPV6RECVPKTINFO option is s...

Introduction Akamai's Smooth Delivery is a network performance enhancement initiative spearheaded by the Protocol Optimization team. It consists of two parts - each focused on reducing congestion while enhancing network performance. 1. TCP Pacing - The topic of this post 2. Rate Limiting -...

kernel: a null pointer dereference in net/dccp/output.c:dccp_write_xmit() leads to a system crash

A null pointer dereference in dccpwritexmit function in net/dccp/output.c in the Linux kernel allows a local user to cause a denial of service by a number of certain crafted system calls...

CVE-2018-0054

On QFX5000 Series and EX4600 switches, a high rate of Ethernet pause frames or an ARP packet storm received on the management interface fxp0 can cause egress interface congestion, resulting in routing protocol packet drops, such as BGP, leading to peering flaps. The following log message may also...

CVE-2018-0054

CVE-2018-0054 affects Juniper Networks Junos OS on QFX5000 Series and EX4600 switches. A high rate of Ethernet pause frames or ARP storms on the management interface (fxp0) can cause egress congestion, leading to routing-protocol drops (e.g., BGP) and peering flaps. Affected releases include many...

UBUNTU-CVE-2017-2634

It was found that the Linux kernel's Datagram Congestion Control Protocol DCCP implementation before 2.6.22.17 used the IPv4-only inetskrebuildheader function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the syst...
