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.

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. > Signed-off-by: Fabrice Fontaine Committed to 2023.02.x and 2023.08.x, thanks. -- Bye, Peter Korsgaard _______________________________________________ buildroot mailing list buildroot@buildroot.org https://lists.buildroot.org/mailman/listinfo/buildroot
