- String not null terminated: 572834
- Dereference before null check: 572919 572847
- Buffer not null terminated: 572891
- Argument cannot be negative: 573009 572928 572868
1. Swap out strdup() for a malloc() and memcpy(). Then nul terminate the string before tokenizing. Fixes CID: 572834
1. When cleaning the path, check that the path pointer is not null before using it. 2. Move the strlen of path. 3. Remove the second check of path, and just loop over it. Fixed CID: 572847
1. After getting the user's pw info, don't check that the shell value is null. We've already use it at that point. Fixes CID: 572919
1. When copying the shell, leave a byte free in the dest buffer. Fill it with a null. Fixes CID: 572891
1. Due to not checking the result of fseek(), it is possible to try to malloc() -1 bytes of storage. Checking the return from fseek() and erring if negative. 2. Changing the check between the result of fseek() and fread() to match signedness. Adding some casting, as at that point the fseek() result is always positive. Fixes CIDs: 573009 572928 572868
