+
+finger segfaults when it comes across a netgroup entry in /etc/passwd.
+A netgroup entry doesn't include many of the fields in a normal passwd
+entry, so pw->pw_gecos is set to NULL, which causes finger to core
+dump.
+
+Here is part of a /etc/passwd file with a netgroup entry:
+
+nobody:x:65534:65534:nobody:/nonexistent:/bin/sh
++@operator
+
+This patch sidesteps what finger considers a malformed passwd entry:
