Exploited in the wild: not listed in CISA KEV
EPSS: 6.0% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2008-08-15 · updated 2026-06-16
Weakness: CWE-119

Description

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: 4.4.0, 4.4.1, 4.4.2, 4.4.3, 4.4.4, 4.4.5 (+10)
