Mandriva Linux Security Advisory 2015-032 - sapi/cgi/cgi_main.c in the CGI component in PHP through 5.4.36, 5.5.x through 5.5.20, and 5.6.x through 5.6.4, when mmap is used to read a.php file, does not properly consider the mapping's length during processing of an invalid file that begins with a # character and lacks a newline character, which causes an out-of-bounds read and might allow remote attackers to obtain sensitive information from php-cgi process memory by leveraging the ability to upload a.php file or trigger unexpected code execution if a valid PHP script is present in memory locations adjacent to the mapping. Use-after-free vulnerability in the process_nested_data function in ext/standard/var_unserializer.re in PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5 allows remote attackers to execute arbitrary code via a crafted unserialize call that leverages improper handling of duplicate numerical keys within the serialized properties of an object. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-8142. The exif_process_unicode function in ext/exif/exif.c in PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5 allows remote attackers to execute arbitrary code or cause a denial of service via crafted EXIF data in a JPEG image. The updated php packages have been upgraded to the 5.5.21 version which is not vulnerable to these issues. Additionally, the timezonedb package has been upgraded to the latest 2015.1 version, the php-suhosin package has been upgraded to the latest 0.9.37.1 and the PECL packages which requires so has been rebuilt for php-5.5.21.
