{"id":"UBUNTU-CVE-2025-57812","details":"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.","modified":"2026-04-22T16:05:44.135818Z","published":"2025-11-12T00:00:00Z","related":["USN-7877-1","USN-7878-1"],"upstream":["CVE-2025-57812"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-57812"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-57812"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2025/11/12/1"},{"type":"REPORT","url":"https://github.com/OpenPrinting/libcupsfilters/security/advisories/GHSA-jpxg-qc2c-hgv4"},{"type":"REPORT","url":"https://github.com/OpenPrinting/libcupsfilters/security/advisories/GHSA-rc6w-jmvv-v7gx"},{"type":"REPORT","url":"https://github.com/OpenPrinting/libcupsfilters/security/advisories/GHSA-fmvr-45mx-43c6"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7877-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7878-1"}],"affected":[{"package":{"name":"cups-filters","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/cups-filters@1.8.3-2ubuntu3.5+esm3?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.8.3-2ubuntu3.5+esm3"}]}],"versions":["1.0.76-1","1.1.0-1","1.1.0-1build1","1.3.0-1","1.4.0-1","1.5.0-1","1.6.0-1","1.7.0-1","1.8.1-1","1.8.2-1","1.8.2-2","1.8.2-2ubuntu2","1.8.2-2ubuntu3","1.8.3-2ubuntu1","1.8.3-2ubuntu2","1.8.3-2ubuntu3","1.8.3-2ubuntu3.1","1.8.3-2ubuntu3.4","1.8.3-2ubuntu3.5","1.8.3-2ubuntu3.5+esm1","1.8.3-2ubuntu3.5+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"cups-browsed","binary_version":"1.8.3-2ubuntu3.5+esm3"},{"binary_name":"cups-filters","binary_version":"1.8.3-2ubuntu3.5+esm3"},{"binary_name":"cups-filters-core-drivers","binary_version":"1.8.3-2ubuntu3.5+esm3"},{"binary_name":"libcupsfilters1","binary_version":"1.8.3-2ubuntu3.5+esm3"},{"binary_name":"libfontembed1","binary_version":"1.8.3-2ubuntu3.5+esm3"}],"availability":"Available
