[FIXED] Access (write) violation / buffer overrun in LLTextureFetchWorker::doWork()
The trouble lines are:
U8 * buffer = (U8 *) ALLOCATE_MEM(LLImageBase::getPrivatePool(), total_size);
if (cur_size > 0)
{
memcpy(buffer, mFormattedImage->getData(), cur_size);
}
If 'cur_size > mHttpReplyOffset + append_size' then 'total_size -= src_offset' will cause
total_size to be smaller than cur_size causing a write access violation on the memcpy.
Since the response is invalid it seemed best to make it follow the other failed partial condition.
