Description Mark J. Cox 2007-09-14 10:32:56 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2007-4887 to the following vulnerability:


The dl function in PHP 5.2.4 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a long string in the library parameter. NOTE: there are limited usage scenarios under which this would be a vulnerability.

Comment 1 Joe Orton 2007-09-14 10:41:47 UTC

The argument passed to the dl() function must always be under the control of the
script author, so this is not treated as a security issue.

Comment 2 Tomas Hoger 2007-11-29 14:29:51 UTC

This problem was addressed in PHP 5.2.5, patches:
