Detailsinfo

A vulnerability classified as problematic has been found in Tesseract up to 5.5.3. This affects the function GENERIC_2D_ARRAY::DeSerializeSize of the file src/ccstruct/matrix.h of the component Deserialization. The manipulation with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on availability. The summary by CVE is:

Tesseract is an open source OCR engine. Prior to 5.5.4, GENERIC_2D_ARRAY::DeSerializeSize in src/ccstruct/matrix.h reads matrix dimensions as signed int32_t values and compares them only with UINT16_MAX, allowing negative values to reach ResizeNoInit. Negative dimensions or a 65535 by 65535 product can create inconsistent allocation state and later out-of-bounds accesses while loading a crafted traineddata file, causing denial of service. This issue is fixed in version 5.5.4.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-119340 since 10/29/2026. The exploitability is told to be easy.
