CVE-2014-5459:
It was reported that the pear utility insecurely used the /tmp/ directory for cache data. A local attacker could use this flaw to perform a symbolic link attack against a user (typically the root user) running a pear command, causing an arbitrary file to be overwritten, possibly leading to a denial of service.

CVE-2014-3597:
Multiple buffer overflows in the php_parserr function in ext/standard/dns.c in PHP before 5.4.32 and 5.5.x before 5.5.16 allow remote DNS servers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted DNS record, related to the dns_get_record function and the dn_expand function. NOTE: this issue exists because of an incomplete fix for CVE-2014-4049.
