Hi,

The following vulnerability was published for
libcupsfilters/cups-filters.

CVE-2025-64503[0]:
| 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 (Common Vulnerabilities & Exposures) id in your changelog entry.
