The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3321-1 advisory.
A path traversal vulnerability in KubeVirt versions up to 0.56 (and 0.55.1) on all platforms allows a user able to configure the kubevirt to read arbitrary files on the host filesystem which are publicly readable or which are readable for UID 107 or GID 107. /proc/self/<> is not accessible. (CVE-2022-1798)
Authorization Bypass Through User-Controlled Key in GitHub repository emicklei/go-restful prior to v3.8.0.
(CVE-2022-1996)
runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. A bug was found in runc prior to version 1.1.2 where runc exec --cap
created processes with non-empty inheritable Linux process capabilities, creating an atypical Linux environment and enabling programs with inheritable file capabilities to elevate those capabilities to the permitted set during execve(2). This bug did not affect the container security sandbox as the inheritable set never contained more capabilities than were included in the container’s bounding set. This bug has been fixed in runc 1.1.2. This fix changes runc exec --cap
behavior such that the additional capabilities granted to the process being executed (as specified via --cap
arguments) do not include inheritable capabilities. In addition, runc spec
is changed to not set any inheritable capabilities in the created example OCI spec (config.json
) file. (CVE-2022-29162)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
