Summary
libjpeg6b vulnerabilities
Details

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)
