Notes:
|
|
|
|
- Reproduces on Windows Server 2003 and Windows 7
|
|
|
|
- The crash occurs due to a memcpy with an invalid source buffer.
|
|
|
|
- The invalid source buffer is actually indicative of an invalid size
|
|
being used in a pointer calculation at 3126A360 (wwlib.dll
|
|
12.0.6707.5000). This invalid size can also be seen in ecx at the time
|
|
of access violation.
|
|
|
|
- The large size parameter can result in a stack-based buffer overflow.
|
|
|
|
- Alternatively, if the copy operation succeeds (by using a size value
|
|
large enough to result in an out-of-bounds source buffer, but not so
|
|
large to cause an access violation during copy), then it is also
|
|
possible to get an arbitrary free from later usage of controlled
|
|
pointers in the destination buffer.
|
|
|
|
- The crashing test case was created using a chunk reordering
|
|
strategy, and does not cleanly minimize (106 bit change from original
|
|
file).
