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 value, an attacker can cause CUPS-Filter 1.x’s tool to write beyond the bounds of an array. First, a PDF with a large width value causes to become large. Next, the calculation of overflows, resulting in a small value. Then, is allocated with the small size. Finally, calls , which attempts to write to outside of its buffer size (out of bounds write). In libcupsfilters, the maintainers found the same 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.
