------------------------------------------------------------------------- Debian LTS Advisory DLA-3731-1 [email protected] https://www.debian.org/lts/security/ Colin Watson February 01, 2024 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : man-db Version : 2.8.5-2+deb10u1 CVE ID :
Debian Bug : 926450 948238 1061870

man-db provides the man command used for reading manual pages.

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.
