> USN-8882-1: Tesseract vulnerabilities

[SOURCE] Ubuntu Security Notices [DATE: 06/10/2026 12:50] [LANGUAGE: EN]

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)

It was discovered that Tesseract did not properly validate layer sizes in
crafted .traineddata models. An attacker could possibly use this issue to
execute arbitrary code. (CVE-2026-88049)

It was discovered that Tesseract incorrectly handled negative character
codes in crafted .traineddata models. An attacker could possibly use this
issue to cause Tesseract to crash, resulting in a denial of service.
(CVE-2026-88050)

It was discovered that Tesseract did not properly validate vector sizes in
crafted .traineddata models. An attacker could possibly use this issue to
execute arbitrary code. (CVE-2026-88051)

It was discovered that Tesseract did not properly validate character IDs in
crafted .traineddata models. An attacker could possibly use this issue to
execute arbitrary code. (CVE-2026-88052)

It was discovered that Tesseract did not properly validate classifier
counts in crafted .traineddata models. An attacker could possibly use this
issue to execute arbitrary code. (CVE-2026-88053)

It was discovered that Tesseract incorrectly handled empty network layers
in crafted .traineddata models. An attacker could possibly use this issue to
cause Tesseract to crash, resulting in a denial of service.
(CVE-2026-88054)
