Use after free in audio in Google Chrome prior to 80.0.3987.149 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

The version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 80.0.361.69. It is, therefore, affected by multiple vulnerabilities:

  - A use-after-free error exists in the WebGL component of Microsoft Edge (Chromium). An unauthenticated,     remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption.
    (CVE-2020-6422)

  - A use-after-free error exists in the media component of Microsoft Edge (Chromium). An unauthenticated,     remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption.
    (CVE-2020-6424)

  - A use-after-free error exists in the audio component of Microsoft Edge (Chromium). An unauthenticated,     remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption.
    (CVE-2020-6427)

In addition, Microsoft Edge (Chromium) is also affected by several additional vulnerabilities and errors including additional use-after-free vulnerabilities, an out-of-bounds read, and an insufficient policy enforcement. Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:1270 advisory.

  - usrsctp: Out of bounds reads in sctp_load_addresses_from_init() (CVE-2019-20503)

  - chromium-browser: Use after free in WebGL (CVE-2020-6422)

  - chromium-browser: Use after free in media (CVE-2020-6424)

  - chromium-browser: Insufficient policy enforcement in extensions (CVE-2020-6425)

  - chromium-browser: Inappropriate implementation in V8 (CVE-2020-6426)

  - chromium-browser: Use after free in audio (CVE-2020-6427, CVE-2020-6428, CVE-2020-6429, CVE-2020-6449)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
