| CVE-2017-20002 | 1 Debian | 2 Debian Linux, Shadow | 2021-06-07 | 4.6 MEDIUM | 7.8 HIGH |
| The Debian shadow package before 1:4.5-1 for Shadow incorrectly lists pts/0 and pts/1 as physical terminals in /etc/securetty. This allows local users to login as password-less users even if they are connected by non-physical means such as SSH (hence bypassing PAM's nullok_secure configuration). This notably affects environments such as virtual machines automatically generated with a default blank root password, allowing all local users to escalate privileges. | |||||
| CVE-2005-4890 | 3 Debian, Redhat, Sudo Project | 4 Debian Linux, Shadow, Enterprise Linux and 1 more | 2020-08-18 | 7.2 HIGH | 7.8 HIGH |
| There is a possible tty hijacking in shadow 4.x before 4.1.5 and sudo 1.x before 1.7.4 via "su - user -c program". The user session can be escaped to the parent session by using the TIOCSTI ioctl to push characters into the input buffer to be read by the next process. | |||||
