The "Security Recommendations" section of
<URL:http://www.openbsd.org/porting.html>
states :
Any software to be installed as a server should be scanned
for buffer overflows, especially unsafe use of
strcat/strcpy/strcmp/sprintf.
The buffer overflow possibilities of strcat/strcpy/sprintf are clear
but given that strcmp(3) neither modifies its parameters nor has any
side effects, this is either a typo (patch attached) or poor wording.
Cheers,
rlr
