EulerOS Virtualization 2.9.0 : curl (EulerOS-SA-2021-1969)

medium Nessus Plugin ID 150264

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- curl 7.63.0 to and including 7.75.0 includes vulnerability that allows a malicious HTTPS proxy to MITM a connection due to bad handling of TLS 1.3 session tickets. When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly(CVE-2021-22890)

- curl 7.1.1 to and including 7.75.0 is vulnerable to an 'Exposure of Private Personal Information to an Unauthorized Actor' by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request(CVE-2021-22876)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected curl packages.
