8 August 2022
Several security issues were fixed in libjpeg-turbo.
Releases
o Ubuntu 16.04 ESM
o Ubuntu 14.04 ESM
Packages
o libjpeg-turbo - library for handling JPEG files
Details
It was discovered that libjpeg-turbo was not properly handling EOF characters,
which could lead to excessive memory consumption through the execution of a
large loop. An attacker could possibly use this issue to cause a denial of
service. ( CVE-2018-11813 )
It was discovered that libjpeg-turbo was not properly performing bounds
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 )
