As businesses and consumers around the world adjust their routines amid the various COVID-19 restrictions, the internet is being used at a scale that the world has never experienced. In addition to millions of people who are now working from home, students all over the world are going online to...
Ubuntu 18.04 LTS : Linux kernel vulnerabilities (USN-4285-1)
The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4285-1 advisory. It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacke...
USN-4286-1: Linux kernel vulnerabilities
It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. CVE-2019-14615 It was discovered that a race condition existed in the Softmac USB Prism54 devi...
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...
Enhancing Network Performance with Packet Pacing
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...
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...
