Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-723 advisory.2024-11-13: CVE-2024-47850 was added to this advisory.
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. (CVE-2024-47076)
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.
Due to the service binding to `*:631 ( INADDR_ANY )`, multiple bugs in `cups-browsed` can be exploited in sequence to introduce a malicious printer to the system. This chain of exploits ultimately enables an attacker to execute arbitrary commands remotely on the target machine without authentication when a print job is started. This poses a significant security risk over the network. Notably, this vulnerability is particularly concerning as it can be exploited from the public internet, potentially exposing a vast number of systems to remote attacks if their CUPS services are enabled. (CVE-2024-47176)
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.) (CVE-2024-47850)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Run 'dnf update cups-filters --releasever 2023.6.20241010' to update your system.See Also
