golang: crypto/tls: slow verification of certificate chains containing large RSA keys
A denial of service vulnerability was found in the Golang Go package caused by an uncontrolled resource consumption flaw. By persuading a victim to use a specially crafted certificate with large RSA keys, a remote attacker can cause a client/server to expend significant CPU time verifying...

Line Trust management vulnerabilities
Line is the instant messaging platform of Line Corporation. A security vulnerability exists in Line prior to version 13.16.0 iOS, which stems from a lack of TLS certificate validation for log transfers in the Finance module of the Line Client...
Mozilla NSS Security Vulnerability
NSS is an underlying cryptography library from the Mozilla Foundation. The library supports a variety of cryptographic algorithms, and the Firefox browser's TLS implementation is based on this library. A security vulnerability exists in Mozilla NSS, which arises when the numeric library for RSA...
An issue was discovered in Python before 3.8.18 3.9.x before 3.9.18 3.10.x before 3.10.13 and 3.11.x before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If a TLS server-side socket is created receives data into the socket buffer and then is closed quickly there is a brief window where the SSLSocket instance will detect the socket as "not connected" and won't initiate a handshake but buffered data will still be readable from the socket buffer. This data will not be authenticated if the server-side TLS peer is expecting client certificate authentication and is indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the buffer. (The TLS connection cannot directly be used for data exfiltration because the vulnerable code path requires that the connection be closed on initialization of the SSLSocket.)

netty: SniHandler 16MB allocation leads to OOM
A flaw was found in Netty's SniHandler while navigating TLS handshake which may permit a large heap allocation if the handler did not have a timeout configured. This issue may allow an attacker to send a client hello packet which would cause the server to buffer large amounts of data per...
PT-2023-5756 · Mbed Tls +1 · Mbed Tls +1
Name of the Vulnerable Software and Affected Versions: Mbed TLS versions 3.2.x through 3.4.x Description: The issue is related to a buffer overflow in Mbed TLS, which can lead to remote code execution. This occurs due to a heap-based buffer overflow vulnerability in the implementation of TLS and...

What Is mTLS? The Essential Guide You Can’t Afford to Miss
Intro: mTLS — The Unsung Hero of Cybersecurity Picture this: You're a secret agent on a high-stakes mission. You have a briefcase full of confidential information that you need to hand over securely. Sure, you could pass it to another agent, but how do you know you can trust them? Here's where mT...
The vulnerability of the DoT protocol’s implementation in BIND DNS servers allows a attacker to induce a service failure.
The vulnerability of the DoT protocol DNS over TLS implementation in BIND DNS servers lies in the insufficient use of the assert function or similar operators when processing requests. Exploiting this vulnerability allows a malicious actor to cause service failures...
