Description Anten Skrabec 2022-02-23 21:13:50 UTC

seatd-launch in seatd 0.6.x before 0.6.4 allows removing files with
escalated privileges when installed setuid root. The attack vector is
a user-supplied socket pathname.

Comment 1 Anten Skrabec 2022-02-23 21:14:15 UTC

Created seatd tracking bugs for this issue:

Affects: fedora-34 [bug 2057701]
Affects: fedora-35 [bug 2057702]

Comment 2 Aleksei Bavshin 2022-02-23 21:31:46 UTC

Not affected:

1. seatd-launch is disabled in our build of seatd. We never shipped the vulnerable component to Fedora users.
2. Even if the user rebuilds the package with `--with server`, SUID bit required for exploiting the vulnerability is not set by default
3. 0.6.4 update is already published for all supported branches
