Subject: logger(1) hiccups on % signs
Index: ucb/logger UNIX 4.3BSD
Description:
Logger(1) mishandles messages containing % signs, treating them as
though they were printf(3) conversion specifiers. As a result,
randomly-formatted strings are logged.
Sometimes you can provoke a core dump.
Repeat-By:
logger -t testing -p user.info
here comes a % sign
here come two %% signs
100%flood insurance 18%dairy cows 5%light bulbs
^D
Fix:
Change
syslog(pri, buf);
to
syslog(pri, "%s", buf);
