Description Jan Lieskovsky 2012-10-12 10:37:03 EDT
An use-after-free flaw was found in the way DOM implementation of KDE libraries performed widget rendering for context menus for a given iframe when the iframe was simultaneously being updated by the parent via JavaScript. A remote attacker could provide a specially-crafted web page that, when opened in an application linked against KDE libraries (such as konqueror), would lead to that application crash or, potentially, arbitrary code execution (depending on the state of the process at the moment the no-longer existing process was accessed) with the privileges of the user running the application.
