check operations, which could lead to a heap-based buffer overread. If a user
or automated system were tricked into opening a specially crafted file, an
attacker could possibly use this issue to cause a denial of service. This
issue only affected Ubuntu 14.04 ESM. (CVE-2018-14498)

It was discovered that libjpeg-turbo was not properly limiting the amount of
main memory being consumed by the system during decompression or multi-pass
compression operations, which could lead to excessive memory consumption. An
attacker could possibly use this issue to cause a denial of service.
(CVE-2020-14152)

It was discovered that libjpeg-turbo was not properly setting variable sizes
when performing certain kinds of encoding operations, which could lead to a
stack-based buffer overflow. If a user or automated system were tricked into
opening a specially crafted file, an attacker could possibly use this issue to
cause a denial of service. (CVE-2020-17541)");
