medium Tenable Self-Hosted Container Security Plugin ID 478481

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - When curl is instructed to download content using the metalink feature, thecontents is verified against a
 hash provided in the metalink XML file.The metalink XML file points out to the client how to get the same
 contentfrom a set of different URLs, potentially hosted by different servers and theclient can then
 download the file from one or several of them. In a serial orparallel manner.If one of the servers hosting
 the contents has been breached and the contentsof the specific file on that server is replaced with a
 modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload.
 It should remove the contents and instead try getting the contentsfrom another URL. This is not done, and
 instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the
 file ondisk. (CVE-2021-22922)

Solution

Update the curl-7.69.1 library and its related packages to version 7.69.1+e2 or later.
