Alpine: libcurl, multiple curl packages: security update to 7.83.1-r0

high Tenable Self-Hosted Container Security Plugin ID 423799

Description

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

- A use of incorrectly resolved name vulnerability fixed in 7.83.1 might remove the wrong file when `--no-
clobber` is used together with `--remove-on-error`. (CVE-2022-27778)

- libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a
trailing dot.curl can be told to receive and send cookies. curl's "cookie engine" can bebuilt with or
without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more
rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if
thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then would
get sent to adifferent and unrelated site or domain. (CVE-2022-27779)

- 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)
