Apache Guacamole: Integer overflow in handling of VNC image buffers
Résumé
Apache Guacamole: Integer overflow in handling of VNC image buffers
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Apache Guacamole 1.5.3 and older do not consistently ensure that values received from a VNC server will not result in integer overflow. If a user connects to a malicious or compromised VNC server, specially-crafted data could result in memory corruption, possibly allowing arbitrary code to be executed with the privileges of the running guacd process.
Users are recommended to upgrade to version 1.5.4, which fixes this issue.
