According to the versions of the curl packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned     about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl     built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation.
    (CVE-2022-27781)

  - libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed     that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for     subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were     left out from the configuration match checks, making themmatch too easily. (CVE-2022-27782)

  - A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and     curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP     requests to this, or other servers to which the cookies match, create requests that become larger than the     threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead     returns an error.This denial state might remain for as long as the same cookies are kept, match and     haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also     would match for `bar.example.com`, making it it possible for a 'sister server' to effectively cause a     denial of service for a sibling site on the same second level domain using this method. (CVE-2022-32205)

  - curl < 7.84.0 supports 'chained' HTTP compression algorithms, meaning that a serverresponse can be     compressed multiple times and potentially with different algorithms. The number of acceptable 'links' in     this 'decompression chain' was unbounded, allowing a malicious server to insert a virtually unlimited     number of compression steps.The use of such a decompression chain could result in a 'malloc bomb',     makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of     memory errors. (CVE-2022-32206)

  - When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by     finalizing the operation with a rename from a temporary name to the final target file name.In that rename     operation, it might accidentally *widen* the permissions for the target file, leaving the updated file     accessible to more users than intended. (CVE-2022-32207)

  - When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly.
    This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject     data to the client. (CVE-2022-32208)
