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 Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-993320 advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1291 advisory.

    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. (CVE-2025-57812)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.
