CVE-2011-4114

CVE-2011-4114 describes a vulnerability in the PAR::Packer module (before version 1.012) for Perl, where the par_mktmpdir function creates temporary files in a predictably named directory without proper ownership and permission checks. This allows a local attacker to overwrite files when another user extracts a PAR packed program. With a CVSS score of 3.3, this is a low-severity vulnerability requiring local access and medium attack complexity, potentially leading to partial integrity and availability impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
