Vulnerability Scan Summary
shadow: Unauthorized modification of account information
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200411-09
(shadow: Unauthorized modification of account information)
Martin Schulze reported a flaw in the passwd_check() function in
"libmisc/pwdcheck.c" which is used by chfn and chsh.
A logged-in local user with an expired password may be able to use chfn and
chsh to change his standard shell or GECOS information (full name, phone
number...) without being required to change his password.
There is no known workaround at this time.
All shadow users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/shadow-4.0.5-r1"
Threat Level: Low
