"It was discovered that Qt incorrectly handled certain PPM images. If a
user or automated system were tricked into opening a specially crafted
PPM file, a remote attacker could cause Qt to crash, resulting in a
denial of service. This issue only affected Ubuntu 16.04 LTS and
Ubuntu 18.04 LTS. (CVE-2018-19872)

It was discovered that Qt incorrectly handled certain text files. If a
user or automated system were tricked into opening a specially crafted
text file, a remote attacker could cause Qt to crash, resulting in a
denial of service. This issue only affected Ubuntu 19.10.
(CVE-2019-18281)

It was discovered that Qt incorrectly searched for plugins in the
current working directory. An attacker could possibly use this issue
to execute arbitrary code. (CVE-2020-0569)

It was discovered that Qt incorrectly searched for libraries relative
to the current working directory. An attacker could possibly use this
issue to execute arbitrary code. This issue only affected Ubuntu
19.10. (CVE-2020-0570).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
