CVE-2018-7186: Debian Linux
Critical severity, CVSS 9.8. EPSS: 3.4% chance of exploitation in the next 30 days.
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.
