CVE-2018-1116
Matthias Gerstner of the SUSE security team found a local information disclosure and denial of service caused by trusting client-submitted UIDs when referencing processes.
CVE-2019-6133
Jann Horn of Google Project Zero found that a kernel vulnerability (Slowfork) allowed local privilege escalation. (This problem was also mitigated by changes to how start_time for forked process are handled in Linux.)
CVE-2026-4897
Pavel Kohout, Aisle Research found that a local user provide a specially
crafted, excessively long input to the polkit-agent-helper-1 setuid binary
via standard input (stdin).
This unbounded input can lead to an out-of-memory (OOM) condition,
resulting in a Denial of Service (DoS) for the system.
For Debian 9 stretch, these problems have been fixed in version 0.105-18+deb9u3.
We recommend that you upgrade your policykit-1 packages.
