GLSA-202401-06 : CUPS filters: Remote Code Execution

high Nessus Plugin ID 187652

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202401-06 (CUPS filters: Remote Code Execution)

 - cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. If you use the Backend Error Handler (beh) to create an accessible network printer, this security vulnerability can cause remote code execution. `beh.c` contains the line `retval = system(cmdline) >> 8;` which calls the `system` command with the operand `cmdline`.
 `cmdline` contains multiple user controlled, unsanitized values. As a result an attacker with network access to the hosted print server can exploit this vulnerability to inject system commands which are executed in the context of the running server. This issue has been addressed in commit `8f2740357` and is expected to be bundled in the next release. Users are advised to upgrade when possible and to restrict access to network printers in the meantime. (CVE-2023-24805)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

All cups-filters users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=net-print/cups-filters-1.28.17-r2
