Double free in ICU in Google Chrome prior to 91.0.4472.77 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

The remote Ubuntu 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5156-1 advisory.

    It was discovered that ICU contains a double free issue. An attacker could use this issue to cause a     denial of service or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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