[GLSA-200606-02] shadow: Privilege escalation Vulnerability Scan
Vulnerability Scan Summary
shadow: Privilege escalation
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200606-02
(shadow: Privilege escalation)
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.
