Hirschmann HiOS Switches Classic Buffer Overflow (CVE-2019-12260)

This vulnerability could lead to a buffer overflow of up to a full TCP receive-window by default, 10k-64k depending on version. The buffer overflow happens in the task calling recv/recvfrom/recvmsg. Applications that pass a buffer equal to or larger than a full TCP-window are not susceptible to...

Yamux Memory Exhaustion Vulnerability via Active::pending_frames property

Summary Attack scenario The Rust implementation of the Yamux stream multiplexer uses a vector for pending frames. This vector is not bounded in length. Every time the Yamux protocol requires sending of a new frame, this frame gets appended to this vector. This can be remotely triggered in a numbe...

kernel: net: tls: avoid hanging tasks on the tx_lock

A denial-of-service flaw was found in the Linux kernel's TLS implementation. An adversarial network receiver can keep the TCP receive window RWIN at zero for extended periods, causing a thread holding the txlock to sleep indefinitely. Other tasks waiting for this lock become hung, leading to syst...
