CVE-2011-4116: _is_safe in the File::Temp module for Perl does not properly handle symlinks.

Security readout for executives and security teams

CVE-2011-4116 concerns Perl's File::Temp module incorrectly judging symlink-related paths as safe. The public bundle does not provide CVSS, fixed versions, or confirmed exploitation. Treat it as an exposure-check item for systems running Perl code that creates temporary files or directories in shared or attacker-influenced locations. Most likely exposure is Perl applications, scripts, build tooling, or packaged software using File::Temp. Risk is higher where temporary paths are in shared writable directories or path components can be influenced by untrusted local users. The affected version range is not identified in the bundle. Handle as a targeted inventory and maintenance item, not an emergency based on this bundle alone. Prioritize internet-facing production build systems, shared hosting, CI workers, and multi-user servers where Perl temporary-file handling may cross trust boundaries. Mitigation focus: Check current File::Temp and Perl vendor guidance for CVE-2011-4116.; Upgrade File::Temp or Perl packages if your vendor identifies a fixed release.; Avoid shared writable temporary directories for sensitive workflows where practical..
