Description Alexander Bergmann 2023-08-31 06:54:00 UTC

CVE-2023-4641

When gpasswd(1) asks for the new password, it asks twice (as is usual for confirming the new password).  Each of those 2 password prompts uses agetpass() to get the password.  If the second agetpass() fails, the first password, which has been copied into the 'static' buffer 'pass' via STRFCPY(), wasn't being zeroed.
