Use-after-free vulnerability in the _zend_shared_memdup function in zend_shared_alloc.c in the OPcache extension allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.
The build_tablename function in pgsql.c in the PostgreSQL (aka pgsql) extension does not validate token extraction for table names, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted name.
The vulnerability can be triggered when parsing a PHAR file at phar.c:623. The "buf_len" is obtained from the phar file and passed into php_var_unserialize() as the max argument. Under normal php_var_unserialize() circumstances, YYCURSOR will always be <= max. This however can be bypassed when processing a malform phar with a buf_len that is shorter then the string to be unserialized resulting in a memory info leak.
