Small praise for modern compilers - A case of Ubuntu printing vulnerability that wasn’t

The report details discovery and exploitation of a buffer-overflow bug in the deprecated ippusbxd IPP-over-USB daemon on Ubuntu 22.04. The author builds a PoC by emulating a malicious USB printer (using PAPPL and a Raspberry Pi Zero) that reports an oversized media-size value, triggering a segfault in ippusbxd; however, compiler mitigations (FORTIFY_SOURCE and -Wstringop-overflow) cause a detected abort rather than reliable code execution, and ippusbxd has been superseded by the memory-safe ipp-usb implementation.
