According to its banner, the version of PHP installed on the remote host is 5.3.x earlier than 5.3.14, and is, therefore, potentially affected the following vulnerabilities :
An integer overflow error exists in the function âphar_parse_tarfileâ in the file âext/phar/tar.câ. This error can lead to a heap-based buffer overflow when handling a maliciously crafted TAR file. Arbitrary code execution is possible due to this error. (CVE-2012-2386)
A weakness exists in the âcryptâ function related to the DES implementation that can allow brute-force attacks. (CVE-2012-2143)
Several design errors involving the incorrect parsing of PHP PDO prepared statements could lead to disclosure of sensitive information or denial of service.
(CVE-2012-3450)
A variable initialization error exists in the file âext/openssl/openssl.câ that can allow process memory contents to be disclosed when input data is of length zero. (CVE-2012-6113)
