Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2023-01-18 04:48:04 UTC
CVE-2018-14628 (

An information leak vulnerability was discovered in Samba's LDAP server. Due to missing access control checks, an authenticated but unprivileged attacker could discover the names and preserved attributes of deleted objects in the LDAP store.

Doesn't seem like fixes ever made it to git.

Hm, new branch, are we able to stabilize? If not, are we sure there's no fixes in older branches that we'd be able to stabilize?
Comment 4 Ben Kohler gentoo-dev 2023-11-28 16:11:46 UTC
I think we're ok to start stabilization on 4.19.3, I don't know of any outstanding regressions on the new series.
