Name of the Vulnerable Software and Affected Versions: D-Link DIR-825AC G1 devices affected versions not specified Description: The issue exists due to insufficient input validation in the D-Link router firmware, allowing a remote attacker to bypass compartmentalization between the host network a...

NewStart CGSL CORE 5.05 / MAIN 5.05 : kernel-rt Multiple Vulnerabilities (NS-SA-2019-0165)

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has kernel-rt packages installed that are affected by multiple vulnerabilities: - Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information...

EulerOS 2.0 SP8 : kernel (EulerOS-SA-2019-1792)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel vmlinuz, the core of any Linux operating system. The kernel handles the basic functions of the...

SUSE-SU-2019:1924-1 Security update for the Linux Kernel (Live Patch 33 for SLE 12 SP1)

This update for the Linux Kernel 3.12.74-6064110 fixes several issues. The following security issues were fixed: - CVE-2019-11477: Jonathan Looney discovered that the TCPSKBCBskb-tcpgsosegs value was subject to an integer overflow when handling TCP Selective Acknowledgments SACKs. A remote attack...

BSA-2019-828

Security Advisory ID : BSA-2019-828 Component : TCP SACK Revision : 2.0 An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment SACK segments. While processing SACK segments, the Linux kernel's socket buffer SKB da...

Kernel: tcp: excessive resource consumption while processing SACK blocks allows remote denial of service

An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment SACK segments. While processing SACK segments, the Linux kernel's socket buffer SKB data structure becomes fragmented, which leads to increased resource...

The vulnerability of the TCP Selective Acknowledgment mechanism in the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the TCP Selective Acknowledgment mechanism in the Linux operating system arises due to a segmentation error in the retransmission queue. Exploiting this vulnerability allows an attacker to cause a service failure by sending a specially crafted sequence of SACK packets...

TCP SACK Panic - Linux Kernel Vulnerability

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...

Vulnerabilities fixed in Linux kernel (SACK PANIC)

Netflix has identified a number of vulnerabilities in the Linux kernel. A malicious party could potentially exploit them to cause a denial-of-service. The vulnerabilities relate to the "minimum segment size" MMS and TCP Selective Acknowledgement SACK capabilities. The most serious of these...

Linux kernel denial of service vulnerability (CNVD-2019-18512)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A resource management error vulnerability exists in the way the network subsystem in the Linux kernel handles the TCP Selective Acknowledgment fragment. An attacker...
