NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Debian.

In Wireshark through 2.6.2, the create_app_running_mutex function in wsutil/file_util.c calls SetSecurityDescriptorDacl to set a NULL DACL, which allows attackers to modify the access control arbitrarily.
