The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4124-1 advisory.
A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests. (CVE-2022-41723)
containerd is an open source container runtime. A bug was found in containerd prior to versions 1.6.18 and 1.5.18 where supplementary groups are not set up properly inside a container. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container. Downstream applications that use the containerd client library may be affected as well. This bug has been fixed in containerd v1.6.18 and v.1.5.18. Users should update to these versions and recreate containers to resolve this issue.
Users who rely on a downstream application that uses containerd’s client library should check that application for a separate advisory and instructions. As a workaround, ensure that the USER $USERNAME
Dockerfile instruction is not used. Instead, set the container entrypoint to a value similar to ENTRYPOINT [su, -, user]
to allow su
to properly set up supplementary groups. (CVE-2023-25173)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
