Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5281-1 advisory.

 It was discovered that some OpenSC smart card drivers mishandled memory when performing certain decoding operations. An attacker could possibly use this issue to cause a denial of service or other unspecified impact. This issue only affected Ubuntu 16.04 ESM and Ubuntu 18.04 ESM. (CVE-2019-15945, CVE-2019-15946)

 It was discovered that some OpenSC smart card drivers had buffer overflow vulnerabilities. An attacker could possibly use this issue to cause a denial of service or other unspecified impact. (CVE-2020-26570, CVE-2020-26571, CVE-2020-26572)

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

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