you donot have complete picture and you incomplete research is
just making everyone confused. i better like to take reference
from the old advisory that gives atleast clear background

http://www.rapid7.com/advisories/R7-0004/index.html

about calm check "manager.c" of clam 0.15

    242 if(strbcasestr(filename, ".zip")) {
    243 char *args[] = { "unzip", "-P", "clam", "-o", (char *)
filename, NULL };
    244 if((userprg = getargl(opt, "unzip")))
    245 ret = clamav_unpack(userprg, args, tmpdir, user, opt);
    246 else
    247 ret = clamav_unpack("unzip", args, tmpdir, user, opt);

clam use unzip utility outside its process space. if unzip itself is
vulnerable (not in case of linux) then clam may face similar problem

Fprot is perfect!
