CVE-2013-0162

CVE-2013-0162 describes a local file overwrite vulnerability in the diff_pp function of the ruby_parser gem (versions 3.1.1 and earlier) for Ruby. An attacker could exploit this by creating a symlink to an arbitrary file, allowing them to overwrite it due to predictable temporary file names in /tmp. This vulnerability has a low severity CVSS score (AV:L/AC:L/Au:N/C:N/I:P/A:N), indicating local access and low attack complexity, with potential for partial integrity impact. There is no evidence of active exploitation, no known public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
