Is this about the strange looking syslog calls in shared/output.c? I have found them
too (boast boast), and I believe that they are no vulnerabilities at all, as the
offending data will always pass through this construct:

while((pt = strchr(vbuff, '%')))
    *pt = '_';

(For the non-programmers out there, it changes all instances of "%" in vbuff to "_".)
