kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service
An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments. If the Maximum Segment Size MSS of a TCP connection was set to low values, such as 48 bytes, it can leave as little as 8 bytes for the user data, which significantly increas...
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...
CVE-2019-7229
The ABB CP635 HMI uses two different transmission methods to upgrade its firmware and its software components: "Utilization of USB/SD Card to flash the device" and "Remote provisioning process via ABB Panel Builder 600 over FTP." Neither of these transmission methods implements any form of...

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...

Kernel: tcp: integer overflow while processing SACK blocks allows remote denial of service
An integer overflow 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. Each fragment is about TCP maximum segment size MSS...

UBUNTU-CVE-2019-11477
Jonathan Looney discovered that the TCPSKBCBskb-tcpgsosegs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments SACKs. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182,...
UBUNTU-CVE-2019-11478
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...
bind: Limiting simultaneous TCP clients is ineffective
A flaw was found in the way bind implemented tunable which limited simultaneous TCP client connections. A remote attacker could use this flaw to exhaust the pool of file descriptors available to named, potentially affecting network connections and the management of files such as log files or zone...
The vulnerability of the microprogrammed programmable logic controller Modicon, related to the use of insufficiently random values, allows a intruder to intercept TCP connections.
The vulnerability of the microprogrammed programmable logic controller Modicon is related to the use of insufficiently random values. Exploiting this vulnerability could allow a malicious actor to intercept TCP connections remotely...
