The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4743 advisory.

  • squid: Improper input validation in request allows for proxy manipulation (CVE-2019-12520)

  • squid: Off-by-one error in addStackElement allows for heap buffer overflow and crash (CVE-2019-12521)

  • squid: Improper input validation in URI processor (CVE-2019-12523)

  • squid: Improper access restriction in url_regex may lead to security bypass (CVE-2019-12524)

  • squid: Heap overflow issue in URN processing (CVE-2019-12526)

  • squid: Information Disclosure issue in FTP Gateway (CVE-2019-12528)

  • squid: Out of bounds read in Proxy-Authorization header causes DoS (CVE-2019-12529)

  • squid: Denial of service in cachemgr.cgi (CVE-2019-12854)

  • squid: Buffer overflow in URI processor (CVE-2019-18676)

  • squid: Cross-Site Request Forgery issue in HTTP Request processing (CVE-2019-18677)

  • squid: HTTP Request Splitting issue in HTTP message processing (CVE-2019-18678)

  • squid: Information Disclosure issue in HTTP Digest Authentication (CVE-2019-18679)

  • squid: Mishandled HTML in the host parameter to cachemgr.cgi results in insecure behaviour (CVE-2019-18860)

  • squid: DoS in TLS handshake (CVE-2020-14058)

  • squid: Request smuggling and poisoning attack against the HTTP cache (CVE-2020-15049)
