Summary

Off-by-one error in the invoke function in IcedTeaScriptablePluginObject.cc in IcedTea-Web 1.1.x before 1.1.7, 1.2.x before 1.2.2, 1.3.x before 1.3.1, and 1.4.x before 1.4.1 allows remote attackers to obtain sensitive information, cause a denial of service (crash), or possibly execute arbitrary code via a crafted webpage that triggers a heap-based buffer overflow, related to an error message and a "triggering event attached to applet." NOTE: the 1.4.x versions were originally associated with CVE-2013-4349, but that entry has been MERGED with this one.
