Openssh · Gsi-Openssh-Server · CVE-2019-7639
**Name of the Vulnerable Software and Affected Versions**
gsi-openssh-server version 7.9p1
**Description**
An issue allows logins to succeed with a valid username and an incorrect password when PermitPAMUserChange is set to yes in the /etc/gsissh/sshd config file, despite recording a failure entry in the /var/log/messages file.
**Recommendations**
For gsi-openssh-server version 7.9p1, consider setting PermitPAMUserChange to no in the /etc/gsissh/sshd config file as a temporary workaround to prevent logins with incorrect passwords.
