https://notcve.org/view.php?id=CVE-2018-15686
A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. Affected releases are systemd versions up to and including 239. Una vulnerabilidad en unit_deserialize de systemd permite que un atacante proporcione estados arbitrarios en la reejecución de systemd mediante NotifyAccess. Esto puede emplearse para influenciar incorrectamente la ejecución de systemd y podría conducir a un escalado de privilegios root. • https://www.exploit-db.com/exploits/45714 http://www.securityfocus.com/bid/105747 https://access.redhat.com/errata/RHSA-2019:2091 https://access.redhat.com/errata/RHSA-2019:3222 https://access.redhat.com/errata/RHSA-2020:0593 https://github.com/systemd/systemd/pull/10519 https://lists.apache.org/thread.html/r1b103833cb5bc8466e24ff0ecc5e75b45a705334ab6a444e64e840a0%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2018/11/msg00017.html https://security.gentoo.org/gl • CWE-20: Improper Input Validation CWE-502: Deserialization of Untrusted Data •
