Perl 5.10.x DoS via NULL Pointer Dereference in getpeername, readdir, closedir, getsockname, rewinddir, tell, or telldir
Perl 5.10.x allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an ability to inject arguments into a (1) getpeername, (2) readdir, (3) closedir, (4) getsockname, (5) rewinddir, (6) tell, or (7) telldir function call.
