CWE-20  (opens in a new tab)

How to fix?

Upgrade Ubuntu:16.04 afflib to version 3.7.7-3ubuntu0.1~esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream afflib package and not the afflib package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

The af_get_page() function in lib/afflib_pages.cpp in AFFLIB (aka AFFLIBv3) through 3.7.16 allows remote attackers to cause a denial of service (segmentation fault) via a corrupt AFF image that triggers an unexpected pagesize value.
