SUSE SLES11 Security Update : curl (SUSE-SU-2021:14707-1)

medium Nessus Plugin ID 150519

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES11 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2021:14707-1 advisory.

 - 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 Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected curl-openssl1, libcurl4-openssl1 and / or libcurl4-openssl1-32bit packages.
