json-web-token library is vulnerable to a JWT algorithm confusion attack
Summary The json-web-token library is vulnerable to a JWT algorithm confusion attack. Details On line 86 of the 'index.js' file, the algorithm to use for verifying the signature of the JWT token is taken from the JWT token, which at that point is still unverified and thus shouldn't be trusted. To...

New SSH Vulnerability
This is interesting: For the first time, researchers have demonstrated that a large portion of cryptographic keys used to protect data in computer-to-server SSH traffic are vulnerable to complete compromise when naturally occurring computational errors occur while the connection is being...
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...
