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.
