The format value has to be a string literal, every time.
Otherwise, you are not using these functions correctly. To reinforce this fact, I putrestrict over every non-contrib example of this I could find.
The log message contains user-controlled strings that could include
things like terminal control characters. Space characters in the
command path are now also escaped.
Command line arguments that contain spaces are surrounded with
single quotes and any literal single quote or backslash characters
are escaped with a backslash. This makes it possible to distinguish
multiple command line arguments from a single argument that contains
spaces.
Issue found by Matthieu Barjole and Victor Cutillas of Synacktiv
(https://synacktiv.com).
The numeric fields in struct sudo_lbuf are now unsigned so that
wraparound is defined, this make the overflow checks simpler.
Problem deteced by oss-fuzz using the fuzz_sudoers fuzzer.
Renamed __malloc -> sudo_malloclike, __printflike -> sudo_printflike,
__printf0like -> sudo_printf0like.
Add sudo_noreturn instead of __attribute__((__noreturn__)).
We do not use stdnoreturn.h since it has been deprecated in C23
in favor of the [[noreturn]] attribute.
