Race conditions occur frequently in signal handlers, since they are asynchronous actions. These race conditions may have any number of root-causes and symptoms. (from TCCLASP-5_4_7_10)

Code with TOCTOU - Time of check, Time of use - culnerability involving stat(). The TOCTOU check occurs with the call of stat() on line 41 and the use is the call of fopen() on line 49. An attacker can simply exploit this vulnerabilty using a symlink: erase the file and make a symbolic link to th...

A file is accessed multiple times by name in a publically accessible directory. A race condition exists between the accesses where an attacker can replace the file referenced by the name.

Tempfile creation should be done in a safe way. To be safe, the temp file function should open up the temp file with appropriate access control. The temp file function should also retain this quality, while being resistant to race conditions. (from TCCLASP-5_6_20_10)
