Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-080 advisory.

An issue was discovered in dbus-broker before 31. It depends on c-uitl/c-shquote to parse the DBus service's Exec line. c-shquote contains a stack-based buffer over-read if a malicious Exec line is supplied. (CVE-2022-31212)

An issue was discovered in dbus-broker before 31. Multiple NULL pointer dereferences can be found when supplying a malformed XML config file. (CVE-2022-31213)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update dbus-broker --releasever=2023.0.20230222 ' to update your system.
