Описание
A flaw was found in polkit. A local user can exploit this by providing 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.
Отчет
A moderate severity issue, a denial of service flaw exists in polkit where a local attacker can exhaust system memory. This vulnerability arises from the polkit-agent-helper-1 setuid binary processing excessively long input via standard input without size limitations, leading to an out-of-memory condition.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
