FreeBSD : FreeBSD -- jail(2) information leak (46a29f83-cb47-11ee-b609-002590c1f29c)

high Nessus Plugin ID 190576

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 46a29f83-cb47-11ee-b609-002590c1f29c advisory.

 - The jail(2) system call has not limited a visiblity of allocated TTYs (the kern.ttys sysctl).
 This gives rise to an information leak about processes outside the current jail. Attacker can get information about TTYs allocated on the host or in other jails. Effectively, the information printed by pstat -t may be leaked. (CVE-2024-25941)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
