An update is available for qt5-qtwebsockets.
This update affects Rocky Linux 8.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list

Security Fix(es):

  • qt: XML entity expansion vulnerability (CVE-2015-9541)

  • qt5-qtwebsockets: websocket implementation allows only limited size for frames and messages therefore attacker can cause DOS (CVE-2018-21035)

  • qt: files placed by attacker can influence the working directory and lead to malicious code execution (CVE-2020-0569)

  • qt: files placed by attacker can influence the working directory and lead to malicious code execution (CVE-2020-0570)

  • qt5: incorrectly calls SSL_shutdown() in OpenSSL mid-handshake causing denial of service in TLS applications (CVE-2020-13962)
