For first function addGlob and addPattern are not described in manual
http://pl2.php.net/manual/en/class.ziparchive.php

ext/zip/php_zip.c
1629 	/* 1 == glob, 2==pcre */
1630 	if (type == 1) {
1631 	if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s|la",
1632 	&pattern, &pattern_len, &flags, &options) == FAILURE) {
1633 	return;
1634 	}
1635 	} else {
1636 	if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s|sa",
1637 	&pattern, &pattern_len, &path, &path_len, &options) == FAILURE) {

There are no GLOB flags validation like in php/glob(). So limit flags only to
GLOB_MARK|GLOB_NOSORT|GLOB_NOCHECK|GLOB_NOESCAPE|GLOB_BRACE|GLOB_ONLYDIR|GLOB_ERR

like
http://pl2.php.net/manual/en/function.glob.php

    * GLOB_MARK - Adds a slash to each directory returned
    * GLOB_NOSORT - Return files as they appear in the directory (no
sorting)
    * GLOB_NOCHECK - Return the search pattern if no files matching it
were found
    * GLOB_NOESCAPE - Backslashes do not quote metacharacters
    * GLOB_BRACE - Expands {a,b,c} to match 'a', 'b', or 'c'
    * GLOB_ONLYDIR - Return only directory entries which match the pattern
    * GLOB_ERR - Stop on read errors (like unreadable directories), by
default errors are ignored.



Test script:
---------------
The crash come, when we run libc/glob(3) function with incorrect flag.
Tested also on linux/ubuntu and (netbsd)
