Synopsis
The remote web server uses a version of PHP that is affected by multiple vulnerabilities.
Description
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 'phar_parse_tarfile' in the file 'ext/phar/tar.c'. 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 'crypt' 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 'ext/openssl/openssl.c' that can allow process memory contents to be disclosed when input data is of length zero. (CVE-2012-6113)
Solution
Upgrade to PHP version 5.3.14 or later.
