Synopsis ========
A security issue in shadow allows a local user to perform certain actions with escalated privileges.
Background ==========
shadow provides a set of utilities to deal with user accounts.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/shadow < 4.0.15-r2 >= 4.0.15-r2
Description ===========
When the mailbox is created in useradd, the "open()" function does not receive the three arguments it expects while O_CREAT is present, which leads to random permissions on the created file, before fchmod() is executed.
Impact ======
Depending on the random permissions given to the mailbox file which is at this time owned by root, a local user may be able to open this file for reading or writing, or even executing it, maybe as the root user.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All shadow users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/shadow-4.0.15-r2"
References ==========
