Debian 10 LTS DLA-3594-1 Critical: CUPS Buffer Overflow and Access Issues

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.
