Details
It was discovered that Tesseract incorrectly handled crafted .traineddata
models. An attacker could possibly use this issue to cause Tesseract to
crash, resulting in a denial of service. (CVE-2026-73067)
It was discovered that Tesseract did not properly validate dimensions in
crafted .traineddata models. An attacker could possibly use this issue to
execute arbitrary code. (CVE-2026-73066)
It was discovered that Tesseract did not properly limit token lengths in
crafted .traineddata models. An attacker could possibly use this issue to
execute arbitrary code. (CVE-2026-88047)
It was discovered that Tesseract did not properly validate layer dimensions
in crafted .traineddata models. An attacker could possibly use this issue to
execute arbitrary code. (CVE-2026-88048)
