kernel: integer overflow in tcp_ack_update_rtt in net/ipv4/tcp_input.c

A flaw was reported in the Linux kernel's TCP subsystem while calculating a packet round trip time, when a sysctl parameter /proc/sys/net/ipv4/tcpminrttwlen is set incorrectly. This causes an integer overflow which can lead to a denial Of service DOS attack...

QEMU: slirp: OOB buffer access while emulating tcp protocols in tcp_emu()

A heap buffer overflow issue was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the tcpemu routine while emulating IRC and other protocols. An attacker could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential...

bind: TCP Pipelining doesn't limit TCP clients on a single connection

A flaw was found in the way bind limited the number of TCP clients that can be connected at any given time. A remote attacker could use one TCP client to send a large number of DNS requests over a single connection, causing exhaustion of the pool of file descriptors available to named, and...

The vulnerability of TCP protocols in real-time operating systems like Wind River VxWorks allows attackers to execute arbitrary code.

The vulnerability of the TCP protocol in real-time operating systems like Wind River VxWorks is related to errors in the TCP Urgent Pointer. Exploiting this vulnerability allows a malicious actor to execute arbitrary code by sending specially crafted TCP packets...

The vulnerability of TCP protocols in real-time operating systems like Wind River VxWorks allows attackers to execute arbitrary code.

The vulnerability of the TCP protocol in real-time operating systems like Wind River VxWorks stems from errors in the TCP Urgent Pointer during the “connect” operation when connecting to a remote host. Exploiting this vulnerability allows an attacker to execute arbitrary code by sending specially...

CVE-2019-15989

A vulnerability in the implementation of the Border Gateway Protocol BGP functionality in Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service DoS condition. The vulnerability is due to incorrect processing of a BGP update message that contains a...

DEBIAN-CVE-2019-18625

An issue was discovered in Suricata 5.0.0. It was possible to bypass/evade any tcp based signature by faking a closed TCP session using an evil server. After the TCP SYN packet, it is possible to inject a RST ACK and a FIN ACK packet with a bad TCP Timestamp option. The client will ignore the RST...

DEBIAN-CVE-2019-18792

An issue was discovered in Suricata 5.0.0. It is possible to bypass/evade any tcp based signature by overlapping a TCP segment with a fake FIN packet. The fake FIN packet is injected just before the PUSH ACK packet we want to bypass. The PUSH ACK packet containing the data will be ignored by...
