Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. The Rack::Sendfile middleware logs unsanitized header values from the X-Sendfile-Type header. An attacker can exploit this by injecting escape sequences such as newline characters into the header, resulting in log injection. This vulnerability has been...

CVE-2026-49427

Pages belonging to largepage shared memory objects were not explicitly wired. When sendfile2 transmitted such an object with the SFNOCACHE flag, it freed the underlying pages after transmission even though existing mappings still referred to them. An unprivileged local user can abuse the bug to...

goshs has ACL Bypass & Path Traversal

Summary sendFile derives the served filename from the raw request path while opening the file from the cleaned path, so appending a trailing slash empties the derived name and defeats both the never-serve rule for the ACL file and the block list. Finding Medium: trailing-slash ACL and hidden-file...
