{"affected":[{"product":"tesseract","source":"CNA: GitHub_M","vendor":"tesseract-ocr","versions":[{"status":"affected","version":"< 5.5.3"}]}],"cveId":"CVE-2026-119341","cwes":["CWE-763"],"description":"Tesseract is an open source OCR engine. Prior to 5.5.4, ReadAdaptedClass in src/classify/adaptive.cpp raw-reads an ADAPT_CLASS_STRUCT from a pre-adapted-template .a file without neutralizing TempProtos and Config pointer fields before any destructor path. When the legacy engine is selected, classify_use_pre_adapted_templates is enabled, and an attacker can write the output-basename .a file, the success or rejection path can pass file-controlled pointers to ~ADAPT_CLASS_STRUCT and operator delete, causing memory corruption and denial of service. This issue is fixed in version 5.5.4.","epss":{"date":"2026-11-02","percentile":0.19223,"score":0.0027},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-357f-833m-3f83"}],"kev":null,"metrics":[{"score":0,"severity":"none","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N","version":"3.1"},{"score":0,"severity":"none","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N","version":"3.1"}],"modifiedAt":1793636251600,"publishedAt":1793391896121,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-357f-833m-3f83"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/tesseract-ocr/tesseract/pull/4645"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/tesseract-ocr/tesseract/commit/614e971036d2b95d521057ff63d68d6612429b23"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/tesseract-ocr/tesseract/releases/tag/5.5.4"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-357f-833m-3f83"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/tesseract-ocr/tesseract/commit/614e971036d2b95d521057ff63d68d6612429b23"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/tesseract-ocr/tesseract/pull/4645"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/tesseract-ocr/tesseract/releases/tag/5.5.4"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-357f-833m-3f83"},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":[],"url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-357f-833m-3f83"}],"remediation":[],"revision":"9e636dc7127528a5c0eba91e9987ca009608c5b453c000aff8ac7df2b634487d","sources":[{"modifiedAt":1793631763092,"name":"CNA: GitHub_M","retrievedAt":1793635732708,"url":"https://www.cve.org/CVERecord?id=CVE-2026-119341"},{"modifiedAt":1793636251600,"name":"NVD","retrievedAt":1793643475469,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-119341"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793635737435,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-119341"}],"ssvc":{"assessedAt":1793631739295,"automatable":"yes","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Tesseract: File-controlled pointers still reach `delete` in ADAPT_CLASS_STRUCT destructor","updatedAt":1793643475469}
