CVE-2012-4415 libguac: Stack-based buffer overflow by protocol handling in guac client plug-in
Last modified: 2016-03-04 05:43:43 EST
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).
This issue affects the versions of the libguac package, as shipped with Fedora release of 16 and 17. Please schedule an update.
This issue affects the version of the libguac package, as shipped with Fedora EPEL 6. Please schedule an update.
