An integer overflow flaw leading to a heap based buffer overflow was found in the way PHP's FTP extension parsed file listing FTP server responses. A malicious FTP server could use this flaw to cause a PHP application to crash or, possibly, execute arbitrary code. (CVE-2015-4022)

A flaw was found in the way PHP parsed multipart HTTP POST requests. A specially crafted request could cause PHP to use an excessive amount of CPU time. (CVE-2015-4024)

It was found that certain PHP functions did not properly handle file names containing a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. (CVE-2015-4025)

It was found that certain PHP functions did not properly handle file names containing a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. (CVE-2015-4026)

PCRE library is prone to a heap overflow vulnerability. Due to insufficient bounds checking inside compile_branch(), the heap memory could be overflowed via a crafted regular expression. Since PCRE library is widely used, this vulnerability should affect many applications using it. An attacker may exploit this issue to execute arbitrary code in the context of the user running the affected application. (CVE-2015-2325)
