Type confusion in Blink in Google Chrome prior to 81.0.4044.138 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

The remote CentOS Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:2064 advisory.

  - Type confusion in Blink in Google Chrome prior to 81.0.4044.138 allowed a remote attacker to potentially     exploit heap corruption via a crafted HTML page. (CVE-2020-6464)

  - A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to     memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8,     Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-6831)

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

The version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 81.0.416.72. It is, therefore, affected by multiple vulnerabilities:

  - A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to     memory corruption and a potentially exploitable crash. (CVE-2020-6831)

  - Type confusion in Blink in Microsoft Edge (Chromium) allowed a remote attacker to potentially     exploit heap corruption via a crafted HTML page. (CVE-2020-6464)
