Description Andrej Nemec 2018-07-23 08:24:50 UTC
It was found that a local attacker can perform limited reads of arbitrary files as root by manipulating cupsd.conf.

Upstream patch:

https://github.com/apple/cups/commit/d47f6aec436e0e9df6554436e391471097686ecc

Comment 1 Andrej Nemec 2018-07-23 08:31:00 UTC
Created cups tracking bugs for this issue:

Affects: fedora-all [bug 1607293]

Comment 3 Doran Moppert 2018-08-21 03:32:35 UTC
Similar to CVE-2018-4180, this attack vector is only available to users in the cups SystemGroup groups, who can manipulate cupsd.conf using cupsctl.  Impact is further limited when SELinux is enforcing as cupsd operates under a restricted context cupsd_t.
