PHP 5.4.x < 5.4.37 Multiple Vulnerabilities
High Nessus Plugin ID 81080
SynopsisThe remote web server uses a version of PHP that is affected by multiple vulnerabilities.
DescriptionAccording to its banner, the version of PHP 5.4.x installed on the remote host is prior to 5.4.37. It is, therefore, affected by multiple vulnerabilities:
- The CGI component has an out-of-bounds read flaw in file 'cgi_main.c' when nmap is used to process an invalid file that begins with a hash character (#) but lacks a newline character. A remote attacker, using a specially crafted PHP file, can exploit this vulnerability to disclose memory contents, cause a denial of service, or possibly execute code. (CVE-2014-9427)
- A use-after-free memory error exists in the function 'process_nested_data' within 'var_unserializer.re' due to the improper handling of duplicate numerical keys within the serialized properties of an object. A remote attacker, using a crafted unserialize method call, can exploit this vulnerability to execute arbitrary code.
- A flaw exists in function 'exif_process_unicode' within 'exif.c' that allows freeing an uninitialized pointer. A remote attacker, using specially crafted EXIF data in a JPEG image, can exploit this to cause a denial of service or to execute arbitrary code. (CVE-2015-0232)
Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade to PHP version 5.4.37 or later.
