CVE-2024-45723 goTenna Pro ATAK Plugin Use of Cryptographically Weak Pseudo-Random Number Generator

The goTenna Pro ATAK Plugin does not use SecureRandom when generating passwords for sharing cryptographic keys. The random function in use makes it easier for attackers to brute force this password if the broadcasted encryption key is captured over RF. This only applies to the optional broadcast ...

CVE-2023-31147

c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom are unavailable, c-ares uses rand to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not seeded by srand so will generate predictable output. Input from the random number generator i...
