Description Guilherme de Almeida Suckevicz 2020-02-07 20:09:38 UTC
In NetHack before 3.6.5, too long of a value for the SYMBOL 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.

Created nethack tracking bugs for this issue:

Affects: epel-8 [bug 1800738]
Affects: fedora-all [bug 1800739]

Comment 2 Ron Olson 2020-02-07 20:13:45 UTC
3.6.5 fixes all these and has already been pushed to stable for F30 and F31, and is still in testing for EPEL8
