CoreDNS Loop Detection Denial of Service Vulnerability

Executive Summary A Denial of Service vulnerability exists in CoreDNS's loop detection plugin that allows an attacker to crash the DNS server by sending specially crafted DNS queries. The vulnerability stems from the use of a predictable pseudo-random number generator PRNG for generating a secret...

Predictable Seed in Pseudo-Random Number Generator (PRNG)

Overview Affected versions of this package are vulnerable to Predictable Seed in Pseudo-Random Number Generator PRNG in the loop plugin during self-test on server startup. An attacker can cause the DNS server to crash by sending specially crafted DNS queries that exploit the use of a predictable...

CVE-2024-57854

CVE-2024-57854 affects Net::NSCA::Client (Perl) up to version 0.009002. The issue comes from using a non-cryptographically secure random number generator for IVs: v0.003 migrated to Data::Rand::Obscure, which relies on Perl’s rand() and is not suitable for cryptographic purposes. The connected de...
