SCA: security update for onionshare-cli (GHSA-x7wr-283h-5h2v)

high Tenable Cloud Security Plugin ID 420368

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OnionShare is an open source tool that lets you securely and anonymously share files, host websites, and
 chat with friends using the Tor network. Affected versions of the desktop application were found to be
 vulnerable to denial of service via an undisclosed vulnerability in the QT image parsing. Roughly 20 bytes
 lead to 2GB memory consumption and this can be triggered multiple times. To be abused, this vulnerability
 requires rendering in the history tab, so some user interaction is required. An adversary with knowledge
 of the Onion service address in public mode or with authentication in private mode can perform a Denial of
 Service attack, which quickly results in out-of-memory for the server. This requires the desktop
 application with rendered history, therefore the impact is only elevated. This issue has been patched in
 version 2.5. (CVE-2022-21688)
