Name of the Vulnerable Software and Affected Versions
PHP versions prior to 5.3.28
PHP versions 5.4.x prior to 5.4.23
PHP versions 5.5.x prior to 5.5.7
Description
The issue arises from the improper parsing of notBefore and notAfter timestamps in X.509 certificates by the asn1 time to time t function. This can lead to memory corruption, allowing remote attackers to execute arbitrary code or cause a denial of service. The vulnerability is caused by a buffer overflow in the OpenSSL library used by PHP.
Recommendations
For PHP versions prior to 5.3.28, update to version 5.3.28 or later.
For PHP versions 5.4.x prior to 5.4.23, update to version 5.4.23 or later.
For PHP versions 5.5.x prior to 5.5.7, update to version 5.5.7 or later.
