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 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...
