CVE-2018-7186 (opens in a new tab)How to fix?
There is no fixed version for Ubuntu:16.04 leptonlib.
NVD Description
Note: Versions mentioned in the description apply only to the upstream leptonlib package and not the leptonlib package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
Leptonica before 1.75.3 does not limit the number of characters in a %s format argument to fscanf or sscanf, which allows remote attackers to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a long string, as demonstrated by the gplotRead and ptaReadStream functions.
