Description:
Updated nethack packages fix security vulnerabilities:

NetHack 3.6.x before 3.6.4 is prone to a buffer overflow vulnerability when
reading very long lines from configuration files. This affects systems that
have NetHack installed suid/sgid, and shared systems that allow users to
upload their own configuration files (CVE-2019-19905).

In NetHack before 3.6.5, unknown options starting with -de and -i 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 influence command line
options (CVE-2020-5209).

In NetHack before 3.6.5, an invalid argument to the -w command line 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 influence
command line options (CVE-2020-5210).

In NetHack before 3.6.5, an invalid extended command in value for the
AUTOCOMPLETE 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 (CVE-2020-5211).

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 (CVE-2020-5212).

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 (CVE-2020-5213).

In NetHack before 3.6.5, detecting an unknown 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 (CVE-2020-5214).

In NetHack before 3.6.6, some out-of-bound values for the hilite_status
option can be exploited (CVE-2020-5254).

The nethack package has been updated to version 3.6.6, fixing these issues
and other bugs. See the upstream release notes for details.
