Patches for the OpenBSD base system are distributed as unified diffs.
|
|
Each patch is cryptographically signed with the
|
|
<a href="https://man.openbsd.org/OpenBSD-7.2/signify.1">signify(1)</a> tool and contains
|
|
usage instructions.
|
|
All the following patches are also available in one
|
|
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/7.2.tar.gz">tar.gz file</a>

<i>All architectures</i>

|
|
In ssh-agent(1)'s PKCS#11 provider support, remote execution was
|
|
possible due to controllable access in low-quality libraries. In
|
|
addition to fixing this, the ability to remotely load PKCS#11
|
|
libraries is now disabled by default (re-enable with
|
|
'-Oallow-remote-pkcs11').
