PHP glob() function denial of service
| php-glob-dos (35437) |  Low Risk |
Description:
PHP is vulnerable to a denial of service, caused by a memory corruption vulnerability in the glob() function. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using an invalid flags parameter to possibly execute arbitrary code on the vulnerable system or cause a denial of service.

- CVE-2007-3806: The glob function in PHP 5.2.3 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via an invalid value of the flags parameter, probably related to memory corruption or an invalid read on win32 platforms, and possibly related to lack of initialization for a glob structure.
