That is All

Tuesday, May 09, 2023

 Lostmon disappeared a few years ago. My way of working and the excessive hours in front of a computer, coupled with high levels of stress and family problems, have led me to a situation where I feel trapped and unable to escape.

Everyone must fight their own inner demons when they come to visit.

Reality is just a point of view, and even when we see reality with our own eyes, it can vary and differ from another observer's perspective.

This has led me to suffer from a mental illness called bipolar schizoaffective disorder. 

Dealing with my enemy is not easy, and I do not want to feed my demons, but computing, PCs, hardware and software, as well as bugs and other technological worlds, have become a mere anecdote in this daily struggle.

Thank you to all who supported me and believed in me one day.

Good luck, peace and harmony to all!

Safari for windows 5.1.7 (7534.57.2) Remote code execution

Saturday, December 14, 2013
############################################
Safari for windows 5.1.7 (7534.57.2) Remote code execution
JavaScriptCore.dll (7534.57.3.3)
Vendor notify: NO Exploit available: Private
Advisore:http://lostmon.blogspot.com.es/2013/12/safari-for-windows-517-7534572-remote.html
 #############################################

Safari for windows is a discontinued product; but in my work ) tecnical support for clients and bussines) i found it installed in serveral machines.

Iit is prone vulnerable to a buffer overflow in  JavaScriptCore.dll that allows remote crash if failed or Remote Code Execution if the exploit is succesfully.

This issue is tiggered when safari try to allocate a large amount of data in  javascript stack memory.
We espect a " out of memory" alert box, but we can bypass or fuzzing this alert and result a RCE.

 i don't like the responses from Apple amd this is a discontinued product.... See Windbg Log for this issue:
