CyberInsider reports on a critical vulnerability in WebRTC implementations identified by Enable Security. This flaw specifically affects how DTLS “ClientHello” messages are processed, making several platforms susceptible to denial-of-service (DoS) attacks. The issue arises from improper source verification of DTLS packets, enabling attackers to disrupt real-time communications. The vulnerability highlights a gap between ICE media consent verification and the DTLS handshake, with WebRTC applications typically relying on UDP, which lacks source verification. Malicious actors can

In Ruby programming, developers often default to using strings, but symbols serve as a useful alternative in specific contexts. This post highlights the distinctions between strings and symbols, noting that symbols are immutable, lightweight identifiers ideal for use as hash keys or method names. Unlike strings, which can be modified and lead to multiple objects in memory, symbols are stored once and provide efficiency when reused. The advantages of symbols include better performance in hash key lookups due to their single-instance storage. However, symbols have limited flexibility
