Feb 13, 2017 · From what I can tell there might be a few different ways to do this: Trick dlopen into thinking that your memory location is a file, even though it never leaves memory. Find some other system call which does what I'm looking for (I don't think this exists). Find some dynamic linking library which can link code directly in memory.

02.02.2018 · We can use dlopen() to this approach because it admits a file descriptor as paramater :). So here is the mix: Contact C&C and download a module; Open a file descriptor to a memory region and write there the .so; Use dlopen() …

I needed a solution to this because I have a scriptable system that has no filesystem (using blobs from a database) and needs to load binary ...

memdlopen is a proof of concept that demonstrate the possibility to fully load a dynamic library from memory on 64 bits linux systems.

This capability is useful for managing modules that are created at runtime, and/or to help implement protection and access controls, etc. Here ...

In this article I introduce shellcode that executes to download a dynamic library from a TCP connection and loads it without ever touching the ...

load dynamically in the code, we have dlopen to do this. I've post this question but I can't still make sure that we could list all lib files.

06.08.2012 · That's asking how to 'hack' dlopen (specifically) to load from memory. I'm wondering about any other possible way to do it. – Qix - MONICA WAS MISTREATED. Aug 6, 2012 at 3:11. Add a comment | 1 Answer Sorted by: Reset to default 9 +50 ...

29.08.2021 · No matter, yes, the simpliest way would be to retrieve only the symbols you need. Your decision. And yes, you can load as many libraries as you want. Read the dlopen manpage on how dependencies are loaded as well (if that is an issue). dlopen simply loads the library file into memory, and dlsym looks for the location of the specified symbol.

dlopen from memory? (3). I don't see why you'd be considering dlopen , since that will require a lot more nonportable code to generate the right object ...

dlopen () The function dlopen () loads the dynamic shared object (shared library) file named by the null-terminated string filename and returns an opaque "handle" for the loaded object. This handle is employed with other functions in the dlopen API, such as dlsym (3), dladdr (3), dlinfo (3), and dlclose ().

Usually you'll load dynamic libraries using a function provided by your platform (e.g. dlopen() or LoadLibrary() ), and the libloading crate provides nice ...

This syscall provide an easy way to get a file descriptor for anonymous memory without requiring a local tmpfs mount-point. In words of the ...

dlopen () The function dlopen () loads the dynamic library file named by the null-terminated string filename and returns an opaque "handle" for the dynamic library. If filename is NULL, then the returned handle is for the main program. If filename contains a slash ("/"), then it is interpreted as a (relative or absolute) pathname.
