CVE-2023-4504

Due to missing boundary checks a heap-based buffer overflow and code execution might be possible by using crafted postscript documents.

CVE-2023-32360

Unauthorized users might be allowed to fetch recently printed documents.

Since this is a configuration fix, it might be that it does not reach you if you are updating the package. Please double check your /etc/cups/cupds.conf file, whether it limits the access to CUPS-Get-Document with something like the following > > AuthType Default > Require user @OWNER @SYSTEM > Order deny,allow > (The important line is the AuthType Default in this section)

For Debian 10 buster, these problems have been fixed in version 2.2.10-6+deb10u9.

We recommend that you upgrade your cups packages.

For the detailed security status of cups please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
