Summary

cups-filters security update

Details

This project provides backends, filters, and other software that was once part of the core CUPS distribution but is no longer maintained by Apple Inc. In addition it contains additional filters and software developed independently of Apple, especially filters for the PDF-centric printing workflow introduced by OpenPrinting and a daemon to browse Bonjour broadcasts of remote CUPS printers to make these printers available locally and to provide backward compatibility to the old CUPS broadcasting and browsing of CUPS 1.5.x and older.

Security Fix(es):

CUPS is a standards-based, open-source printing system, and libcupsfilters contains the code of the filters of the former cups-filters package. In CUPS-Filters versions up to and including 1.28.17 and libcupsfilters versions 2.0.0 through 2.1.1, the 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. An attacker must issue a print job with a crafted TIFF file and control the bytes-per-pixel value of the output format. The vulnerability exists in both CUPS-Filters 1.x and libcupsfilters 2.x. A patch is available in commit b69dfacec7f176281782e2f7ac44f04bf9633cfa.(CVE-2025-57812)

cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. 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.(CVE-2025-64503)

Severity

First, a PDF with a large `MediaBox` width value causes `header.cupsWidth` to become large.

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.

CVE-2025-57812 (GCVE-0-2025-57812)

Title

[BIGSLEEP-434612419] CUPS-Filters has heap-buffer-overflow write in `cfImageLut()`

Summary

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.

Title

[BIGSLEEP-434615384] cups-filters 1.x: out of bounds write in pdftoraster

Summary

cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. 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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
