CVE-2020-5210 describes a buffer overflow vulnerability in NetHack versions prior to 3.6.5. This flaw, triggered by an invalid argument to the -w command line option, can lead to application crashes, or potentially remote code execution and privilege escalation. With a CVSS score of 7.8 (High), it presents a significant risk, particularly on systems where NetHack is installed with suid/sgid permissions or on shared systems allowing command-line option manipulation. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, users are strongly advised to upgrade to NetHack 3.6.5 to mitigate this risk.
