Debian 10 Buster DLA-3731-1 Moderate Man-DB Sandboxing Fix

man-db 2.7.6.1-3 added AppArmor confinement for filter programs called
by man, and man-db 2.8.0 added a seccomp sandbox to confine subprocesses
that handle untrusted data. These hardening measures caused various
problems that have been fixed in more recent releases: the AppArmor
confinement broke the ability to save compressed cat pages under
/var/cache/man/, while the seccomp sandbox broke Hardened Malloc as well
as systems using mksh-derived shells.

For Debian 10 buster, these problems have been fixed in version
2.8.5-2+deb10u1.

We recommend that you upgrade your man-db packages.
