medium Nessus Plugin ID 152771

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the openSUSE-SU-2021:2810-1 advisory.

 - An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus- daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients. (CVE-2020-12049)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
