>Description:
/usr/sbin/pw coredumps when adding/deleting usernames longer than
30 characters
>How-To-Repeat:
On a system that supports usernames longer than 30 characters (for
example, UT_NAMESIZE is set to 32 and MAXLOGNAME is set to 33), run
the following: "pw useradd testuser.customerservice12345678"
>Fix:
The length of the pfx buffer in the pw_update function in pwupd.c
should be dependent on MAXLOGNAME instead of being hardcoded to 32:
