CVE-2008-3659: PHP

Medium severity, CVSS 6.4. EPSS: 6% chance of exploitation in the next 30 days.

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.

Affected products

• PHP PHP: version 4.4.0 only; version 4.4.1 only; version 4.4.2 only; version 4.4.3 only; version 4.4.4 only; version 4.4.5 only; …
