| CVE-2023-29383 | In Shadow 4.13, it is possible to inject control characters into fields provided to the SUID program chfn (change finger). Although it is not possible to exploit this directly (e.g., adding a new user fails because \n is in the block list), it is possible to misrepresent the /etc/passwd file when viewed. Use of \r manipulations and Unicode characters to work around blocking of the : character make it possible to give the impression that a new user has been added. In other words, an adversary may | [email protected] | 3.3 | 0.43% | 2023-04-14 | 2026-06-17 |
| CVE-2019-19882 | shadow 4.8, in certain circumstances affecting at least Gentoo, Arch Linux, and Void Linux, allows local users to obtain root access because setuid programs are misconfigured. Specifically, this affects shadow 4.8 when compiled using --with-libpam but without explicitly passing --disable-account-tools-setuid, and without a PAM configuration suitable for use with setuid account management tools. This combination leads to account management tools (groupadd, groupdel, groupmod, useradd, userdel, us | [email protected] | 7.8 | 0.50% | 2019-12-18 | 2026-06-16 |
| CVE-2018-7169 | An issue was discovered in shadow 4.5. newgidmap (in shadow-utils) is setuid and allows an unprivileged user to be placed in a user namespace where setgroups(2) is permitted. This allows an attacker to remove themselves from a supplementary group, which may allow access to certain filesystem paths if the administrator has used "group blacklisting" (e.g., chmod g-rwx) to restrict access to paths. This flaw effectively reverts a security feature in the kernel (in particular, the /proc/self/setgrou | [email protected] | 5.3 | 1.62% | 2018-02-15 | 2026-06-16 |
| CVE-2017-12424 | In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts. | [email protected] | 9.8 | 2.66% | 2017-08-04 | 2026-06-16 |
| CVE-2016-6252 | Integer overflow in shadow 4.2.1 allows local users to gain privileges via crafted input to newuidmap. | [email protected] | 7.8 | 0.41% | 2017-02-17 | 2026-06-16 |
