Buffer overflow in MUNGE authentication daemon (versions 0.5 to 0.5.17) allows local attackers to extract cryptographic key material from memory, enabling forgery of credentials to impersonate any user on systems relying on MUNGE for authentication. By sending a crafted message with an oversized address length field, an attacker can corrupt the daemon's internal state and retrieve the MAC subkey used for credential verification. The vulnerability affects Debian Linux and other distributions packaging affected MUNGE versions; patching to 0.5.18 or later is available.
