Description
Description
A flaw was found in dbus. A local attacker can exploit this vulnerability by connecting to an affected service, requesting a response, and stopping socket reads while keeping the connection open. Because the socket transport handles broken pipe write errors as retryable, the application enters a continuous retry loop. This can lead to excessive CPU consumption, resulting in a denial of service (DoS) for the target process.
