GHSA-54MG-VGRP-MWX9 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in Ratpack

Ratpack versions before 1.6.1 generate a session ID using a cryptographically weak PRNG in the JDK's ThreadLocalRandom. This means that if an attacker can determine a small window for the server start time and obtain a session ID value, they can theoretically determine the sequence of session IDs...

CVE-2018-12384: Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG)

When handling a SSLv2-compatible ClientHello request, the server doesn't generate a new random value but sends an all-zero value instead. This results in full malleability of the ClientHello for SSLv2 used for TLS 1.2 in all versions prior to NSS 3.39. This does not impact TLS 1.3...

kernel: Type confusion in drivers/tty/n_tty.c allows for a denial of service

A security flaw was found in the Linux kernel in drivers/tty/ntty.c which allows local attackers ones who are able to access pseudo terminals to lock them up and block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ handler...

ghostscript: subroutines within pseudo-operators must themselves be pseudo-operators (700317)

It was found that ghostscript could leak sensitive operators on the operand stack when a pseudo-operator pushes a subroutine. A specially crafted PostScript file could use this flaw to escape the -dSAFER protection in order to, for example, have access to the file system outside of the SAFER...

Ghostscript 9.26 - Pseudo-Operator Remote Code Execution

I noticed ghostscript 9.26 was released, so had a quick look and spotted some errors. For background, this is how you define a subroutine in postscript: /hello hello\n print def That's simple enough, but because a subroutine is just an executable array of commands, you need to mark it as...
