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 ...

This is a type of architecture initially proposed in 2017, and subsequently developed to analyze existing text and generate new content. Transformer models are powerful language engines that break sentences down into tiny chunks, digest the meaning of each chunk, and then reassemble them into coheren...
What is Grounding? Grounding is the process of using large language models (LLMs) with information that is use-case specific, relevant, and not available as part of the LLM's trained knowledge. It ...
