CVE-2014-3515: Debian Linux

High severity, CVSS 7.5. EPSS: 30.1% chance of exploitation in the next 30 days.

The SPL component in PHP before 5.4.30 and 5.5.x before 5.5.14 incorrectly anticipates that certain data structures will have the array data type after unserialization, which allows remote attackers to execute arbitrary code via a crafted string that triggers use of a Hashtable destructor, related to "type confusion" issues in (1) ArrayObject and (2) SPLObjectStorage.

Affected products

• Debian Debian Linux: version 7.0 only; version 8.0 only
• PHP PHP: before 5.3.29 (fixed in 5.3.29); from 5.4.0, before 5.4.30 (fixed in 5.4.30); from 5.5.0, before 5.5.14 (fixed in 5.5.14)
