CVE-2018-7186 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:19.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream leptonlib package and not the leptonlib package as distributed by Ubuntu.
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.
