Trivial fuzzing of molebox archives revealed a heap overflow decrypting the packed image in moleboxMaybeUnpack. This vulnerability is obviously exploitable for remote arbitrary code execution as NT AUTHORITY\SYSTEM.
|
|
|
|
The attached testcase should cause heap corruption in AvastSvc.exe, please enable page heap if you have trouble reproducing.
|
|
|
|
HEAP[AvastSvc.exe]: ZwAllocateVirtualMemory failed c0000018 for heap 00310000 (base 0E560000, size 0006B000)
|
|
(474.9f8): Access violation - code c0000005 (first chance)
|
|
First chance exceptions are reported before any exception handling.
|
|
This exception may be expected and handled.
