| CVE | 摘要 | 來源 | 最高 CVSS | EPSS % | 公開時間 | 更新時間 |
|---|---|---|---|---|---|---|
| CVE-2017-20002 | 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. | [email protected] | 7.8 | 0.06% | 2021-03-17 | 2024-11-21 |
| CVE-2013-4235 | shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees | [email protected] | 4.7 | 0.06% | 2019-12-03 | 2024-11-21 |
| CVE-2005-4890 | 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. | [email protected] | 7.8 | 0.23% | 2019-11-04 | 2024-11-21 |
| CVE-2011-0721 | Multiple CRLF injection vulnerabilities in (1) chfn and (2) chsh in shadow 1:4.1.4 allow local users to add new users or groups to /etc/passwd via the GECOS field. | [email protected] | 6.4 | 1.42% | 2011-02-19 | 2026-04-29 |
| CVE-2008-5394 | /bin/login in shadow 4.0.18.1 in Debian GNU/Linux, and probably other Linux distributions, allows local users in the utmp group to overwrite arbitrary files via a symlink attack on a temporary file referenced in a line (aka ut_line) field in a utmp entry. | [email protected] | 7.2 | 0.08% | 2008-12-09 | 2026-04-23 |
| CVE-2006-1174 | useradd in shadow-utils before 4.0.3, and possibly other versions before 4.0.8, does not provide a required argument to the open function when creating a new user mailbox, which causes the mailbox to be created with unpredictable permissions and possibly allows attackers to read or modify the mailbox. | [email protected] | 3.7 | 0.10% | 2006-05-28 | 2026-04-16 |
| CVE-2006-1844 | The Debian installer for the (1) shadow 4.0.14 and (2) base-config 2.53.10 packages includes sensitive information in world-readable log files, including preseeded passwords and pppoeconf passwords, which might allow local users to gain privileges. | [email protected] | 2.1 | 0.07% | 2006-04-19 | 2026-04-16 |
| CVE-2004-1001 | Unknown vulnerability in the passwd_check function in Shadow 4.0.4.1, and possibly other versions before 4.0.5, allows local users to conduct unauthorized activities when an error from a pam_chauthtok function call is not properly handled. | [email protected] | 4.6 | 0.07% | 2005-03-01 | 2026-04-16 |
