Package : cups
Version : 2.2.10-6+deb10u9
CVE ID : CVE-2023-4504 CVE-2023-32360
Debian Bug : #1051953
Two issues have been found in cups, the Common UNIX Printing System(tm).
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.
