Alpine: multiple rpm packages, py3-rpm: security update to 4.18.0-r0
medium Tenable Self-Hosted Container Security Plugin ID 406944
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- A race condition vulnerability was found in rpm. A local unprivileged user could use this flaw to bypass
the checks that were introduced in response to CVE-2017-7500 and CVE-2017-7501, potentially gaining root
privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as
system availability. (CVE-2021-35937)
- A symbolic link issue was found in rpm. It occurs when rpm sets the desired permissions and credentials
after installing a file. A local unprivileged user could use this flaw to exchange the original file with
a symbolic link to a security-critical file and escalate their privileges on the system. The highest
threat from this vulnerability is to data confidentiality and integrity as well as system availability.
(CVE-2021-35938)
- It was found that the fix for CVE-2017-7500 and CVE-2017-7501 was incomplete: the check was only
implemented for the parent directory of the file to be created. A local unprivileged user who owns another
ancestor directory could potentially use this flaw to gain root privileges. The highest threat from this
vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2021-35939)
