> if the env variable has been mangled this can lead to an overflow. The solution proposed is to replace it with a call to strtol() with error checking.
Note: This is *not at all* the problem/solution. This was an initial misunderstanding/misreporting. The subject describes it better. See #2290859 for details.
The embargo got lifted. @ahanwate can you please remove the "security" group from #2290859 ? I am unable to do this myself. The bug should become public now. Thanks!
