Security researchers Tyson Smith and Jesse Schwartzentruber used the Address Sanitizer tool while fuzzing to discover a use-after-free error resulting in a crash. This is a result of a pair of NSSCertificate structures being added to a trust domain and then one of them is removed while they are still in use by the trusted cache. This crash is potentially exploitable. This issue was addressed in the Network Security Services (NSS) library in version 3.16.2, shipping on affected platforms.
