A pair of zero-day vulnerabilities in Google Chrome (CVE-2020-15999) and Microsoft Windows (CVE-2020-17087) were chained together and exploited in the wild in targeted attacks. A separate Chrome vulnerability (CVE-2020-16009) has also been exploited in the wild.

CVE-2020-15999, CVE-2020-17087: Google Chrome FreeType and Microsoft Windows Kernel Zero Days Exploited in the Wild

Inappropriate implementation in V8 in Google Chrome prior to 86.0.4240.183 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-2020:4974 advisory.

  - Use after free in user interface in Google Chrome prior to 86.0.4240.183 allowed a remote attacker to     potentially exploit heap corruption via a crafted HTML page. (CVE-2020-16004)

  - Insufficient policy enforcement in ANGLE in Google Chrome prior to 86.0.4240.183 allowed a remote attacker     to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-16005)

  - Inappropriate implementation in V8 in Google Chrome prior to 86.0.4240.183 allowed a remote attacker to     potentially exploit heap corruption via a crafted HTML page. (CVE-2020-16006, CVE-2020-16009)

  - Stack buffer overflow in WebRTC in Google Chrome prior to 86.0.4240.183 allowed a remote attacker to     potentially exploit stack corruption via a crafted WebRTC packet. (CVE-2020-16008)

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

Multiple security issues were discovered in the Chromium web browser, which could result in the execution of arbitrary code, denial of service or information disclosure.

Update to 87.0.4280.66. Fixes bugs and security holes. Yay!

Update to Chromium 86. A few big things here :

1. Upstream has made hardware accelerated video support (VAAPI) for Linux possible without patches. One key difference is that the patchset used previously in Fedora enabled it by default and upstream's approach disables it by default. To enable Hardware accelerated video in chromium, open this link in chromium :

chrome://flags/#enable-accelerated-video-decode

Be sure it is turned on. Note that not all GPUs are supported.

2. All the security fixes you expect with a major release:
CVE-2020-15967 CVE-2020-15968 CVE-2020-15969 CVE-2020-15970 CVE-2020-15971 CVE-2020-15972 CVE-2020-15990 CVE-2020-15991 CVE-2020-15973 CVE-2020-15974 CVE-2020-15975 CVE-2020-15976 CVE-2020-6557 CVE-2020-15977 CVE-2020-15978 CVE-2020-15979 CVE-2020-15980 CVE-2020-15981 CVE-2020-15982 CVE-2020-15983 CVE-2020-15984 CVE-2020-15985 CVE-2020-15986 CVE-2020-15987 CVE-2020-15992 CVE-2020-15988 CVE-2020-15989 CVE-2020-16000 CVE-2020-16001 CVE-2020-16002 CVE-2020-16003
