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 10 buster, these problems have been fixed in version 0.105-25+deb10u2.
We recommend that you upgrade your policykit-1 packages.
