|Multiple buffer overflows in PHP before 5.2.1 allow attackers to cause
a denial of service and possibly execute arbitrary code via
unspecified vectors in the (1) session, (2) zip, (3) imap, and (4)
sqlite extensions; (5) stream filters; and the (6) str_replace, (7)
mail, (8) ibase_delete_user, (9) ibase_add_user, and (10)
ibase_modify_user functions. NOTE: vector 6 might actually be an
integer overflow (CVE-2007-1885). NOTE: as of 20070411, vector (3)
might involve the imap_mail_compose function (CVE-2007-1825).
