Critical: php55

Issue Overview:

A heap-based buffer overflow was found in glibc’s __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. (CVE-2015-0235)

A use-after-free flaw was found in the unserialize() function of PHP’s DateTimeZone implementation. A malicious script author could possibly use this flaw to disclose certain portions of server memory. (CVE-2015-0273)
