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.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is an out-of-bounds read/write issue in the imagetoraster filter of CUPS-Filters and libcupsfilters when processing TIFF image files. Specifically, the pixel buffer is allocated based on a calculated bytes-per-pixel value, but the processing function uses a fixed multiplier of 3, which can cause memory outside the allocated buffer to be accessed if the bytes-per-pixel is set to 1. An attacker can exploit this by submitting a print job with a specially crafted TIFF file and specific print job options that trigger this condition.


How can this vulnerability impact me? :

The vulnerability can lead to out-of-bounds memory access during the processing of print jobs with crafted TIFF files. This could potentially cause data corruption or leakage of sensitive information from memory, impacting the integrity and confidentiality of the system handling the print jobs.


What immediate steps should I take to mitigate this vulnerability?

Apply the available patch referenced by commit b69dfacec7f176281782e2f7ac44f04bf9633cfa to update the vulnerable functions in CUPS-Filters or libcupsfilters. Avoid processing print jobs with untrusted or crafted TIFF files that could trigger the vulnerability until patched.
