https://notcve.org/view.php?id=CVE-2009-5147
29 Mar 2017 — DL::dlopen in Ruby 1.8, 1.9.0, 1.9.2, 1.9.3, 2.0.0 before patchlevel 648, and 2.1 before 2.1.8 opens libraries with tainted names. DL::dlopen en Ruby 1.8, 1.9.0, 1.9.2, 1.9.3, 2.0.0 en versiones anteriores a patchlevel 648, y 2.1 en versiones anteriores a 2.1.8 abre librerías con nombres contaminados. It was discovered that Ruby DL::dlopen incorrectly handled opening libraries. An attacker could possibly use this issue to open libraries with tainted names. This issue only applied to Ubuntu 14.04 LTS. • https://github.com/vpereira/CVE-2009-5147 • CWE-20: Improper Input Validation CWE-267: Privilege Defined With Unsafe Actions •
