CVE-2021-22922

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.

Curl is used in command lines or scripts to transfer data.

Security Fix(es):

When curl is instructed to get content using the metalink feature, and a user name and password are used to download the metalink XML file, those same credentials are then subsequently passed on to each of the servers from which curl will download or try to download the contents from. Often contrary to the user's expectations and intentions and without telling the user it happened.(CVE-2021-22923)

The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.

Security Fix(es):

• curl: Content not matching hash in Metalink is not being discarded (CVE-2021-22922)

• curl: Metalink download sends credentials (CVE-2021-22923)

• curl: Bad connection reuse due to flawed path name checks (CVE-2021-22924)

When curl is instructed to download content using the Metalink feature, the contents 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 content from a set of different URLs, potentially hosted by different servers and the client can then download the file from one or several of them. In a serial or parallel manner.

If one of the servers hosting the contents has been breached and the contents of the specific file on that server is replaced with a modified payload, curl should detect this when the hash of the file mismatches after a completed download. It should remove the contents and instead try getting the contents from another URL. This is not done, and instead such a hash mismatch is only mentioned in text and the potentially malicious content is kept in the file on disk.

There is a risk the user does not notice the message and instead assumes the file is fine.
