October-December 2023 Status Report  

This is the last 2023 quarter. As you have probably noticed, this status report comes later than usual and with fewer reports than the preceding quarter. Indeed, please keep in mind that the last quarter of every year is for many members of our community the quarter of the celebrations for Christmas and for the New Year, which implies that those members will spend more time with their families and will have less time for their favorite voluntary software projects. Thus there is less to report and reports tend to arrive later. But finally, here they are.

FreeBSD Errata Notice FreeBSD-EN-24:04.ip  

The race condition can trigger a NULL pointer dereference in the kernel, resulting in a kernel panic.

FreeBSD Errata Notice FreeBSD-EN-24:03.kqueue  

Using kqueue(2) with a process using rfork(2) can panic the system.

FreeBSD Security Advisory FreeBSD-SA-24:02.tty  

Attacker can get information about TTYs allocated on the host or in other jails. Effectively, the information printed by "pstat -t" may be leaked.

FreeBSD Errata Notice FreeBSD-EN-24:02.libutil  

An unprivileged user may bypass the administrator's resource limits and/or CPU mask settings stemming from his login class provided he can run a (setuid) login-like program that: - - Calls setusercontext() with the LOGINSETRESOURCES and/or LOGINSETCPUMASK flags but without LOGINSETUSER (which excludes the use of LOGINSETALL), and with a non-NULL 'pwd' argument. - - Does so before changing the effective user ID to the target user. No programs in FreeBSD's base system, including login(1) and su(1), meet these requirements, but third-party programs may. In particular, sudo(8) does when using the default sudoers(5) plugin configured with the 'use_loginclass' flag enabled. doas(8) does not.

FreeBSD Errata Notice FreeBSD-EN-24:01.tzdata  

An incorrect time will be displayed on a system configured to use one of the affected time zones if the /usr/share/zoneinfo and /etc/localtime files are not updated, and all applications on the system that rely on the system time, such as cron(8) and syslog(8), will be affected. With the default configuration, FreeBSD systems cannot file updates to the installed leap-seconds.list file. Since no leap second was introduced at the end of 2023, the leap-seconds.list file included with all supported FreeBSD releases is still accurate. Moreover, ntpd(8) is able to receive updated leap second information from its peers. However, a diagnostic warning about an expired leap-seconds.list is printed at startup.

FreeBSD Security Advisory FreeBSD-SA-24:01.bhyveload  

In the bhyveload(8) model, the host supplies a to boot with, but the loader scripts generally come from the guest image. A maliciously crafted script could be used to exfiltrate sensitive data from the host accessible to the user running bhyhveload(8), which is often the system root.
