While fuzzing UPX packed files, this crash was discovered resulting in an arbitrary stack-relative write. This vulnerability is obviously remotely exploitable for remote code execution as NT AUTHORITY\SYSTEM.
|
|
|
|
First chance exceptions are reported before any exception handling.
|
|
This exception may be expected and handled.

This decoding loop is trying to modify a value in a stack buffer with an attacker controlled index.
|
|
|
|
The index and Those values are taken verbatim from the input:
|
|
|
|
50 BC C7 00 39 F9 0F B6 47 FB F7 D8 01 04 24 39
|
|

|
90 FC 90 FC 89 DB 9B FC 9B FC 83 E9 ED 83 C4 08

And the value being added is from here:

The bug is that the index is not verified, resulting in an arbitrary write. This is obviously exploitable for arbitrary code execution.
