The remote host is missing an update to the system as announced in the referenced advisory.

Update your system with the appropriate patches or software upgrades.

The following packages are affected: php5 php5-sockets CVE-2011-2483 crypt_blowfish before 1.1, as used in PHP before 5.3.7 on certain platforms, does not properly handle 8-bit characters, which makes it easier for context-dependent attackers to determine a cleartext password by leveraging knowledge of a password hash. CVE-2011-2202 The rfc1867_post_handler function in main/rfc1867.c in PHP before 5.3.7 does not properly restrict filenames in multipart/form-data POST requests, which allows remote attackers to conduct absolute path traversal attacks, and possibly create or overwrite arbitrary files, via a crafted upload request, related to a 'file path injection vulnerability.' CVE-2011-1938 Stack-based buffer overflow in the socket_connect function in ext/sockets/sockets.c in PHP 5.3.3 through 5.3.6 might allow context-dependent attackers to execute arbitrary code via a long pathname for a UNIX socket. CVE-2011-1148 Use-after-free vulnerability in the substr_replace function in PHP 5.3.6 and earlier allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact by using the same variable for multiple arguments.
