Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:1355-1 advisory.

Updated to version 2.2.34.

- CVE-2020-36327: Bundler chooses a dependency source based on the highest gem version number, which means that a rogue gem found at a public source may be chosen (bsc#1185842)

- CVE-2021-43809: rubygem-bundler: remote execution via Gemfile argument injection (bsc#1193578)

Tenable has extracted the preceding description block directly from the SUSE 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

Update the affected ruby2.5-rubygem-bundler package.
