{"cve":"CVE-2025-57812","nvd":{"published":"2025-11-12T19:15:36.753","modified":"2026-10-18T20:10:00.110","status":"Analyzed","description":"CUPS is a standards-based, open-source printing system, and `libcupsfilters` contains the code of the filters of the former `cups-filters` package as library functions to be used for the data format conversion tasks needed in Printer Applications. In CUPS-Filters versions up to and including 1.28.17 and libscupsfilters versions 2.0.0 through 2.1.1, CUPS-Filters's `imagetoraster` filter has an out of bounds read/write vulnerability in the processing of TIFF image files.  While the pixel buffer is allocated with the number of pixels times a pre-calculated bytes-per-pixel value, the function which processes these pixels is called with a size of the number of pixels times 3.  When suitable inputs are passed, the bytes-per-pixel value can be set to 1 and bytes outside of the buffer bounds get processed. In order to trigger the bug, an attacker must issue a print job with a crafted TIFF file, and pass appropriate print job options to control the bytes-per-pixel value of the output format. They must choose a printer configuration under which the `imagetoraster` filter or its C-function equivalent `cfFilterImageToRaster()` gets invoked. The vulnerability exists in both CUPS-Filters 1.x and the successor library libcupsfilters (CUPS-Filters 2.x). In CUPS-Filters 2.x, the vulnerable function is `_cfImageReadTIFF() in libcupsfilters`. When this function is invoked as part of `cfFilterImageToRaster()`, the caller passes a look-up-table during whose processing the out of bounds memory access happens. In CUPS-Filters 1.x, the equivalent functions are all found in the cups-filters repository, which is not split into subprojects yet, and the vulnerable code is in `_cupsImageReadTIFF()`, which is called through `cupsImageOpen()` from the `imagetoraster` tool. A patch is available in commit b69dfacec7f176281782e2f7ac44f04bf9633cfa.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","score":3.7},"cwes":["CWE-125","CWE-787"],"references":["https://github.com/OpenPrinting/cups-filters/blob/3c58463e341b12c9d30d7d3807d2bac1bc595a78/cupsfilters/image-tiff.c#L34","https://github.com/OpenPrinting/cups-filters/blob/3c58463e341b12c9d30d7d3807d2bac1bc595a78/filter/imagetoraster.c#L613","https://github.com/OpenPrinting/libcupsfilters/blob/33421982e10f6a14bc0bab03b80c9cf4660e8d7d/cupsfilters/image-tiff.c#L32","https://github.com/OpenPrinting/libcupsfilters/commit/b69dfacec7f176281782e2f7ac44f04bf9633cfa","https://github.com/OpenPrinting/libcupsfilters/security/advisories/GHSA-jpxg-qc2c-hgv4"],"products":["openprinting:cups-filters","openprinting:libcupsfilters"],"source":"nvd","synced_at":"2026-10-19T22:14:53.307938015+00:00"},"epss":{"cve":"CVE-2025-57812","score":0.00478,"percentile":0.40975,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
