CVE-2006-1990: PHP

Medium severity, CVSS 5.0. EPSS: 10.6% chance of exploitation in the next 30 days.

Integer overflow in the wordwrap function in string.c in PHP 4.4.2 and 5.1.2 might allow context-dependent attackers to execute arbitrary code via certain long arguments that cause a small buffer to be allocated, which triggers a heap-based buffer overflow in a memcpy function call, a different vulnerability than CVE-2002-1396.

Affected products

• PHP PHP: version 4.4.2 only; version 5.1.2 only
