In cups-filters prior to 1.28.18, by crafting a PDF file with a large `MediaBox` value, an attacker can cause CUPS-Filter 1.x’s `pdftoraster` tool to write beyond the bounds of an array. First, a PDF with a large `MediaBox` width value causes `header.cupsWidth` to become large.  Next, the calculation of `bytesPerLine = (header.cupsBitsPerPixel * header.cupsWidth + 7) / 8` overflows, resulting in a small value. Then, `lineBuf` is allocated with the small `bytesPerLine` size. Finally, `convertLineChunked` calls `writePixel8`, which attempts to write to `lineBuf` outside of its buffer size (out of bounds write). In libcupsfilters, the maintainers found the same `bytesPerLine` multiplication without overflow check, but the provided test case does not cause an overflow there, because the values are different. Commit 50d94ca0f2fa6177613c97c59791bde568631865 contains a patch, which is incorporated into cups-filters version 1.28.18."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","baseScore":4.0,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":2.5,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","baseScore":3.3,"baseSeverity":"LOW","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":1.8,"impactScore":1.4}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-787"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:openprinting:cups-filters:*:*:*:*:*:*:*:*","versionEndExcluding":"1.28.18","matchCriteriaId":"1E8D664D-AE1E-4B08-8CB0-91A43C19EE27"},{"vulnerable":true,"criteria":"cpe:2.3:a:openprinting:libcupsfilters:*:*:*:*:*:*:*:*","versionStartIncluding":"2.0.0","versionEndExcluding":"2.1.2","matchCriteriaId":"D664D9C3-6C68-41D2-ADC0-A47B8003B47D"}]}]}],"references":[{"url":"https://github.com/OpenPrinting/cups-filters/blob/aea8d0db017e495b0204433ebdb0e86b4871094c/filter/pdftoraster.cxx#L1620","source":"security-advisories@github.com","tags":["Product"]},{"url":"https://github.com/OpenPrinting/cups-filters/blob/aea8d0db017e495b0204433ebdb0e86b4871094c/filter/pdftoraster.cxx#L1880","source":"security-advisories@github.com","tags":["Product"]},{"url":"https://github.com/OpenPrinting/cups-filters/commit/50d94ca0f2fa6177613c97c59791bde568631865","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/OpenPrinting/cups-filters/security/advisories/GHSA-893j-2wr2-wrh9","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://github.com/OpenPrinting/libcupsfilters/blob/1dd86d835b27ed149b66aee1a4853d1db8a1f44c/cupsfilters/pdftoraster.cxx#L1790","source":"security-advisories@github.com","tags":["Product"]},{"url":"http://www.openwall.com/lists/oss-security/2025/11/12/2","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List","Third Party Advisory"]}]}}]}
