Notes
For some inexplicable reason, this was treated as a standard bug at the time it was discovered, so other vulnerable versions never received patches. This decision is strange because the similar issue VWE-2012-0205 was addressed in the same time period, but was patched in multiple versions.
In addition, this issue was addressed in an existing patch that had already been released, resulting in some users likely not benefitting from the fixes.
