申请一个0x64的chunk,也就是后面存flag的那块chunk被malloc时需要的size。 free这块chunk。free后会这个chunk会放到fastbin或者tcache(glibc较高版本)里面。 调easy()再次malloc申请就会申请到同一块chunk。再利用uaf漏洞,用之前的悬空指针读同一块chunk。 importctypes libc = ctypes.cdll.LoadLibrary('libc.so.6'...
(such as spaces). once these chunks have been broken apart, they can then be recombined in any way desired. since each chunk has become its own independent entity no longer bound by its original context within the larger string block. to accomplish this there are usually built-in methods ...

How streamed responses typically work, with data sent continuously in small chunks. Chunk sizes can be out of your control, so it's important that your code can handle chunks of any size. Chunks sizes are influenced by the following factors: Data source: Sometimes the original data is alread...

The context argument to HTTPServerRequest is now optional, and if a context is supplied the remote_ip attribute is also optional. HTTPServerRequest.body is now always a byte string (previously the default empty body would be a unicode string on python 3). Header parsing now works correctly ...

In this example, we're using theChatOpenAIclass to send a message to the OpenAI API. We're also using thecallmethod to get a stream of message chunks. Each time a new chunk is received, we increment thetokenCountvariable by the length of the chunk's content. At the end, we log the...
