"The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the
openSUSE-SU-2021:1081-1 advisory.
- containerd is a container runtime. A bug was found in containerd versions prior to 1.4.8 and 1.5.4 where
pulling and extracting a specially-crafted container image can result in Unix file permission changes for
existing files in the hosts filesystem. Changes to file permissions can deny access to the expected owner
of the file, widen access to others, or set extended bits like setuid, setgid, and sticky. This bug does
not directly allow files to be read, modified, or executed without an additional cooperating process. This
bug has been fixed in containerd 1.5.4 and 1.4.8. As a workaround, ensure that users only pull images from
trusted sources. Linux security modules (LSMs) like SELinux and AppArmor can limit the files potentially
affected by this bug through policies and profiles that prevent containerd from interacting with specific
files. (CVE-2021-32760)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
