cups-filters vulnerabilities

Libcupsfilters: cups-filters: libcupsfilters: cups image filter process abort via malformed png

A flaw was found in libcupsfilters and cups-filters. The PNG image reading function creates a libpng reader without installing an error recovery handler, causing the CUPS image filter process to abort when processing a malformed PNG file. An unauthenticated attacker could exploit this by submitting a specially crafted PNG print job, leading to denial of service of the in-flight print job.

CUPS rastertopclx Filter Vulnerable to Heap Buffer Overflow Leading to Potential Arbitrary Code Execution

cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. In versions 2.0.1 and prior, a heap-buffer-overflow vulnerability in the rastertopclx filter causes the program to crash with a segmentation fault when processing maliciously crafted input data. This issue can be exploited to trigger memory corruption, potentially leading to arbitrary code execution. This issue has been patched via commit 956283c.

[BIGSLEEP-434615384] cups-filters 1.x: out of bounds write in pdftoraster

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, `convertLineC

[BIGSLEEP-434612419] CUPS-Filters has heap-buffer-overflow write in `cfImageLut()`

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

CVE-2024-47850

CUPS cups-browsed before 2.5b1 will send an HTTP POST request to an arbitrary destination and port in response to a single IPP UDP packet requesting a printer to be added, a different vulnerability than CVE-2024-47176. (The request is meant to probe the new printer but can be used to create DDoS amplification attacks.)

libcupsfilters's cfGetPrinterAttributes5 does not validate IPP attributes returned from an IPP server

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. The `cfGetPrinterAttributes5` function in `libcupsfilters` does not sanitize IPP attributes returned from an IPP server. When these IPP attributes are used, for instance, to generate a PPD file, this can lead to attacker controlled data to be provided to the rest of the CUPS system.

cups-browsed binds to `INADDR_ANY:631`, trusting any packet from any source

CUPS is a standards-based, open-source printing system, and `cups-browsed` contains network printing functionality including, but not limited to, auto-discovering print services and shared printers. `cups-browsed` binds to `INADDR_ANY:631`, causing it to trust any packet from any source, and can cause the `Get-Printer-Attributes` IPP request to an attacker controlled URL. When combined with other vulnerabilities, such as CVE-2024-47076, CVE-2024-47175, and CVE-2024-47177, an attacker can execute arbitrary commands remotely on the target machine without authentication when a malicious printer is printed to.

Command injection in cups-filters

cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. If you use the Backend Error Handler (beh) to create an accessible network printer, this security vulnerability can cause remote code execution. `beh.c` contains the line `retval = system(cmdline) >> 8;` which calls the `system` command with the operand `cmdline`. `cmdline` contains multiple user controlled, unsanitized values. As a result an attacker with network access to the hosted print server can exploit this vulnerability to inject system commands which are executed in the context of the ru
