Package: php5
Version: 5.4.4-14+deb7u11
Severity: important

php5 stable version has a gaping memory leak in SSL handling which was fixed
upstream.

Without this patch, a process which makes repeated FTP-SSL connections will
eventually consume all resources of the server, not limited by PHP's own
memory_limit.
