CVE-2012-4415: Buffer Overflow
First published: Wed Sep 12 2012(Updated: )
A stack based buffer overflow flaw was found in guac client plug-in protocol handling functionality of libguac, a common library used by all C components of Guacamole. A remote attacker could provide a specially-crafted protocol specification to the guac client plug-in that, when processed would lead to guac client crash (denial of service).
