Multiple format string vulnerabilities in the phar extension in PHP 5.3 before 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, or (4) phar_wrapper_open_url functions in ext/phar/stream.c; and the (5) phar_wrapper_open_dir function in ext/phar/dirstream.c, which triggers errors in the php_stream_wrapper_log_error function.

PHP was updated to version 5.3.3 to fix serveral security issues.

Entry for CVE-2010-2094 says :

Multiple format string vulnerabilities in the phar extension in PHP 5.3 before 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, or (4) phar_wrapper_open_url functions in ext/phar/stream.c; and the (5) phar_wrapper_open_dir function in ext/phar/dirstream.c, which triggers errors in the php_stream_wrapper_log_error function.

PECL source code for PHAR extension shares the same code, so it is vulnerable too.

The remote host is affected by the vulnerability described in GLSA-201110-06 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the       CVE identifiers referenced below for details.
  Impact :

    A context-dependent attacker could execute arbitrary code, obtain       sensitive information from process memory, bypass intended access       restrictions, or cause a Denial of Service in various ways.
    A remote attacker could cause a Denial of Service in various ways,       bypass spam detections, or bypass open_basedir restrictions.
  Workaround :

    There is no known workaround at this time.

According to its banner, the version of PHP 5.3 installed on the remote host is older than 5.3.4.  Such versions may be affected by several security issues :
