CVE-2018-19518

An argument injection vulnerability in imap_open() may allow a remote attacker to execute arbitrary OS commands on the IMAP server.

The fix for the CVE-2018-19518 vulnerability included this additional note from the upstream developers:

Starting with 5.6.38, rsh/ssh logins are disabled by default. Use imap.enable_insecure_rsh if you want to enable them. Note that the IMAP library does not filter mailbox names before passing them to rsh/ssh command, thus passing untrusted data to this function with rsh/ssh enabled is insecure.

CVE-2018-19935

A NULL pointer dereference leads to an application crash and a denial of service via an empty string in the message argument to the imap_mail function of ext/imap/php_imap.c.

For Debian 8 Jessie, these problems have been fixed in version 5.6.39+dfsg-0+deb8u1.

We recommend that you upgrade your php5 packages.
