Description

Security researcher Ronald Crane reported seven vulnerabilities affecting released code that he found through code inspection. These included three uses of uninitialized memory, one poor validation leading to an exploitable crash, one read of unowned memory in zip files, and two buffer overflows. These do not all have clear mechanisms to be exploited through web content but are vulnerable if a mechanism can be found to trigger them.
