EulerOS 2.0 SP12 : ruby (EulerOS-SA-2024-2542)

medium Nessus Plugin ID 208354

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the ruby packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 Rubygems.org is the Ruby community's gem hosting service. A Gem publisher can cause a Remote DoS when publishing a Gem. This is due to how Ruby reads the Manifest of Gem files when using Gem::Specification.from_yaml. from_yaml makes use of SafeYAML.load which allows YAML aliases inside the YAML-based metadata of a gem. YAML aliases allow for Denial of Service attacks with so-called `YAML-bombs` (comparable to Billion laughs attacks). This was patched. There is is no action required by users. This issue is also tracked as GHSL-2024-001 and was discovered by the GitHub security lab.(CVE-2024-35221)

Tenable has extracted the preceding description block directly from the EulerOS ruby security advisory.

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 ruby packages.
