Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-055 advisory.

A vulnerability was found in curl. This security flaw allows reusing OAUTH2-authenticated connections without properly ensuring that the connection was authenticated with the same credentials set for this transfer. This issue leads to an authentication bypass, either by mistake or by a malicious actor.
(CVE-2022-22576)

A vulnerability was found in curl. This security flaw allows leaking credentials to other servers when it follows redirects from auth-protected HTTP(S) URLs to other protocols and port numbers. (CVE-2022-27774)

A vulnerability was found in curl. This security flaw occurs due to errors in the logic where the config matching function did not take the IPv6 address zone id into account. This issue can lead to curl reusing the wrong connection when one transfer uses a zone id, and the subsequent transfer uses another.
(CVE-2022-27775)

A vulnerability was found in curl. This security flaw allows leak authentication or cookie header data on HTTP redirects to the same host but another port number. Sending the same set of headers to a server on a different port number is a problem for applications that pass on custom `Authorization:` or `Cookie:`headers. Those headers often contain privacy-sensitive information or data. (CVE-2022-27776)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update --releasever=2022.0.20220504 curl' to update your system.
