Alpine: curl: security update to 7.80.0-r2

critical Tenable Cloud Security Plugin ID 404018

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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)

- The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name
part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For
example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed
into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more.
(CVE-2022-27780)

- 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)
