Description Jan Lieskovsky 2012-09-20 13:05:54 UTC
An integer overflow, leading to heap-based buffer overflow flaw was found in the way journald functionality of systemd, a system and service manager, processed native messages. A local attacker could provide a specially-crafted packet that when processed by systemd would lead to systemd daemon crash or, potentially, arbitrary code execution with the privileges of the user running the daemon.
