VUL-1: CVE-2018-7186 leptonica: Stack-based buffer overflows in gplotRead() and ptaReadStream() when parsing crafted files can lead to denial of service
Last modified: 2018-03-06 23:47:50 UTC
rh#1546029 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.
