opensuse
Calendar Grey November 10, 2018
Dist Opensuse Esm H88
Crucial Fedora patch for kernel resolves memory leak and various vulnerabilities, enhancing system stability and protection.
An update that solves two vulnerabilities and has 16 fixes is now available.

Description

This update for systemd fixes the following issues:

Security issues fixed:

- CVE-2018-15688: A buffer overflow vulnerability in the dhcp6 client of

systemd allowed a malicious dhcp6 server to overwrite heap memory in

- 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. (bsc#1113665)

Non security issues fixed:

- dhcp6: split assert_return() to be more debuggable when hit

- core: skip unit deserialization and move to the next one when

unit_deserialize() fails

- core: properly handle deserialization of unknown unit types (#6476)

- core: don't create Requires for workdir if "missing ok" (bsc#1113083)

- logind: use manager_get_user_by_pid() where appropriate

- logind: rework...
