Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5425-1 advisory.

 Yunho Kim discovered that PCRE incorrectly handled memory when

 handling certain regular expressions. An attacker could possibly use this issue to cause applications using PCRE to expose sensitive information. This issue only affects Ubuntu 18.04 LTS,

 Ubuntu 20.04 LTS, Ubuntu 21.10 and Ubuntu 22.04 LTS. (CVE-2019-20838)

 It was discovered that PCRE incorrectly handled memory when

 handling certain regular expressions. An attacker could possibly use this issue to cause applications using PCRE to have unexpected

 behavior. This issue only affects Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-14155)

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.
