Aladdin Mubaied discovered that the cjpeg utility in libjpeg9 did not properly validate the input image's size. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2016-3616)

It was discovered that the cjpeg utility in libjpeg9 incorrectly handled certain input. An attacker could possibly use these issues to cause a denial of service. (CVE-2018-11212, CVE-2018-11813, CVE-2020-14152, CVE-2020-14153)

It was discovered that the cjpeg utility in libjpeg9 incorrectly handled memory when supplied with certain input. An attacker could possibly use these issues to cause a denial of service or execute arbitrary code. (CVE-2018-11213, CVE-2018-11214)

It was discovered that Libjpeg6b was not properly performing bounds checks when compressing PPM and Targa image files. An attacker could possibly use this issue to cause a denial of service. (CVE-2018-11212)

Chijin Zhou discovered that Libjpeg6b was incorrectly handling the EOF character in input data when generating JPEG files. An attacker could possibly use this issue to force the execution of a large loop, force excessive memory consumption, and cause a denial of service. (CVE-2018-11813)

Sheng Shu and Dongdong She discovered that Libjpeg6b was not properly limiting the amount of memory being used when it was performing decompression or multi-pass compression operations. An attacker could possibly use this issue to force excessive memory consumption and cause a denial of service. (CVE-2020-14152)

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)
