Vulnerability Summary for CVE-2008-3659
Original release date:08/15/2008
Last revised:07/15/2009
Source:
US-CERT/NIST
Overview
Buffer overflow in the memnstr function in PHP 4.4.x before 4.4.9 and PHP 5.6 through 5.2.6 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via the delimiter argument to the explode function. NOTE: the scope of this issue is limited since most applications would not use an attacker-controlled delimiter, but local attacks against safe_mode are feasible.
Description
Overview contains a typo, should read "PHP 5.2 through 5.2.6" not "5.6 through 5.2.6".
Impact
CVSS Severity (version 2.0):
Impact Subscore:
4.9
Exploitability Subscore:
10.0
CVSS Version 2 Metrics:
Access Vector: Network exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type:Allows unauthorized modification; Allows disruption of service
- Official Statement from Red Hat (01/01/1900)
-
The PHP interpreter does not offer a reliable sandboxed security layer (as found in, say, a JVM) in which untrusted scripts can be run any script run by the PHP interpreter must be trusted with the privileges of the interpreter itself. We therefore do not classify this issue as security-sensitive since no trust boundary is crossed.
