CVE-2020-5212 (GCVE-0-2020-5212)

Vulnerability from cvelistv5 – Published: 2020-01-28 17:55 – Updated: 2024-08-04 08:22

Title

NetHack MENUCOLOR configuration file option is subject to a buffer overflow

Summary

In NetHack before 3.6.5, an extremely long value for the MENUCOLOR configuration file option can cause a buffer overflow resulting in a crash or remote code execution/privilege escalation. This vulnerability affects systems that have NetHack installed suid/sgid and shared systems that allow users to upload their own configuration files. Users should upgrade to NetHack 3.6.5.

Severity
