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)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.04 ESM:
libjpeg62                       6b1-4ubuntu1+esm1
