CVE-2013-4248
CVSS v2.0
4.3
Medium
| Vector | AV:N/AC:M/Au:N/C:N/I:P/A:N |
Name of the Vulnerable Software and Affected Versions
PHP versions prior to 5.4.18
PHP versions 5.5.x prior to 5.5.2
Description
The issue arises from the improper handling of a '0' character in a domain name within the Subject Alternative Name field of an X.509 certificate by the openssl x509 parse function. This allows for man-in-the-middle attacks, where an attacker can spoof arbitrary SSL servers using a crafted certificate issued by a legitimate Certification Authority.
Recommendations
For PHP versions prior to 5.4.18, update to version 5.4.18 or later.
For PHP versions 5.5.x prior to 5.5.2, update to version 5.5.2 or later.
