Since sh.rustup.rs has multiple adddresses, the order in the DNS reply can change each time it is resolved (even from a cache), so might be using a different adddress each time. __Martin
FreeBSD Security Advisory FreeBSD-SA-22:01.vt
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 = FreeBSD-SA-22:01.vt Security Advisory The FreeBSD Project Topic: vt console buffer overflow Category: kernel Module: vt Announced: 2022-01-11 Credits:Oleg Bulyzhin Affects:FreeBSD 12.2 and FreeBSD 13.0 Corrected: 2021-09-22 18:41:00 UTC (stable/13, 13.0-STABLE) 2022-01-11 18:15:03 UTC (releng/13.0, 13.0-RELEASE-p6) 2021-09-25 18:15:49 UTC (stable/12, 12.2-STABLE) 2022-01-11 18:33:21 UTC (releng/12.2, 12.2-RELEASE-p12) CVE Name: CVE-2021-29632 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit https://security.FreeBSD.org/>. I. Background FreeBSD's system console is provided by the vt(4) virtual terminal console driver. II. Problem Description Under certain conditions involving use of the highlight buffer while text is scrolling on the console, console data may overwrite data structures associated with the system console or other kernel memory. III. Impact Users with access to the system console may be able to cause system misbehaviour. IV. Workaround No workaround is available. V. Solution Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date, and reboot. Perform one of the following: 1) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the amd64, i386, or (on FreeBSD 13 and later) arm64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install # shutdown -r +10min "Rebooting for a security update" 2) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch https://security.FreeBSD.org/patches/SA-22:01/vt.patch # fetch https://security.FreeBSD.org/patches/SA-22:01/vt.patch.asc # gpg --verify vt.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile your kernel as described in https://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the system. VI. Correction details This issue is corrected by the corresponding Git commit hash or Subversion revision number in the following stable and release branches: Branch/path Hash Revision - - stable/13/ 9352de39c3dcstable/13-n247428 releng/13.0/3e0a1e124169 releng/13.0-n244773 stable/12/r370674 releng/12.2/ r371491 - - For FreeBSD 13 and later: Run the following command to see which files were modified by a particular commit: # git show --stat Or visit the following URL, replacing NN with the hash: https://cgit.freebsd.org/src/commit/?id=NN> To determine the commit count in a working tree (for comparison against nNN in the table above), run: # git rev-list --count --first-parent HEAD For FreeBSD 12 and earlier: Run the following command to see which files were modified by a particular revision, replacing NN with the revision number: # svn diff -cNN --summarize svn://svn.freebsd.org/base Or visit the following URL, replacing NN with the revision number: https://svnweb.freebsd.org/base?view=revision&revision=NN> VII.

Re: FreeBSD Security Advisory FreeBSD-SA-22:01.vt
Sorry for the delay in sending this to the security mailing list. Since the mailing list change over, we've had a few hiccups on delivery to the lists and with this email, we should hopefully be back to a state where we consistently deliver. Again, apologies for the weirdness, but I believe we have ironed out all the wrinkles and will be in a better spot going forward. Thanks to the postmaster team for the work in getting this all sorted.
