             Summary: [patch] app_osplookup.c: Avoid a format truncation.
                 Key: ASTERISK-28804
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28804
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_osplookup
    Affects Versions: 17.3.0, 16.9.0, 13.32.0
            Reporter: Alexander Traud
            Severity: Trivial


The compiler _GCC_ (9.2.1) reports:{code}
app_osplookup.c: In function ‘osp_convert_inout.constprop’:
app_osplookup.c:1011:35: warning: ‘]’ directive output may be truncated writing 1 byte into a region of size between 0 and 255 [-Wformat-truncation=]
             snprintf(dest, destsize, "[%s]", buffer);
                                          ^
app_osplookup.c:1009:35: warning: ‘]:’ directive output may be truncated writing 2 bytes into a region of size between 0 and 255 [-Wformat-truncation=]
             snprintf(dest, destsize, "[%s]:%s", buffer, port);
                                          ^~
{code}ASTERISK-27578 did not find that issue, therefore GCC seems to have improved to detect such issues.
