There exist a stack exhaustion vulnerability in libwireshark.dll, which is
caused by deep recursive call in proto_tree_traverse_post_order function.
gboolean proto_tree_traverse_post_order(proto_tree *tree,
proto_tree_traverse_func func, gpointer data)
{
proto_node *pnode = tree;
proto_node *child;
proto_node *current;
child = pnode->first_child;
while (child != NULL) {
/*
* The routine we call might modify the child, e.g. by
* freeing it, so we get the child's successor before
* calling that routine.
*/
current = child;
child = current->next;
if (proto_tree_traverse_post_order((proto_tree *)current, func, data))
return TRUE;
}
if (func(pnode, data))
return TRUE;
return FALSE;
}
When open the crafted poc file, and click the final http 200 packet the
vulnerability will be trigered. The application will crash.
I have tested this problem in 2.0.1 and 2.0.2.
But the legency version seems not be affected.
