From 5.4.0 until 5.5.4, AppendLinePolygon in src/api/pagerenderer.cpp destroys the caller-owned right-to-left Pta accumulator while receiving it by value, leaving line_top_rtl_pts and line_bottom_rtl_pts dangling. On an upright Hebrew or Arabic page at the default PAGE XML level, POLYGONFLAG with a false skewed_flag enters the vulnerable calls, while LEVELFLAG greater than zero provides an alternative gate. The calls repeatedly read and free the stale object, causing a double free and use after free and allowing corrupted coordinates to reach RecalcPolygonline. This issue is fixed in version 5.5.4."}],"id":"CVE-2026-119338","lastModified":"2026-11-05T03:17:19.860","metrics":{"cvssMetricV40":[{"cvssData":{"Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","Safety":"NOT_DEFINED","attackComplexity":"LOW","attackRequirements":"NONE","attackVector":"LOCAL","availabilityRequirement":"NOT_DEFINED","baseScore":6.9,"baseSeverity":"MEDIUM","confidentialityRequirement":"NOT_DEFINED","exploitMaturity":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","privilegesRequired":"NONE","providerUrgency":"NOT_DEFINED","subAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","userInteraction":"PASSIVE","valueDensity":"NOT_DEFINED","vectorString":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0","vulnAvailabilityImpact":"HIGH","vulnConfidentialityImpact":"LOW","vulnIntegrityImpact":"LOW","vulnerabilityResponseEffort":"NOT_DEFINED"},"source":"security-advisories@github.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-119338","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","timestamp":"2026-11-05T02:40:50.309406Z","version":"2.0.3"}}]},"published":"2026-10-30T21:16:51.797","references":[{"source":"security-advisories@github.com","url":"https://github.com/tesseract-ocr/tesseract/commit/fa52414ff1fd13ae4b00048d2498f9141b0bc2eb"},{"source":"security-advisories@github.com","url":"https://github.com/tesseract-ocr/tesseract/pull/4647"},{"source":"security-advisories@github.com","url":"https://github.com/tesseract-ocr/tesseract/releases/tag/5.5.4"},{"source":"security-advisories@github.com","url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-vf7v-2h4f-6f4j"},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","url":"https://github.com/tesseract-ocr/tesseract/security/advisories/GHSA-vf7v-2h4f-6f4j"}],"sourceIdentifier":"security-advisories@github.com","vulnStatus":"Awaiting Analysis","weaknesses":[{"description":[{"lang":"en","value":"CWE-125"},{"lang":"en","value":"CWE-415"},{"lang":"en","value":"CWE-416"}],"source":"security-advisories@github.com","type":"Secondary"}]}
