  • CVE-2019-9022

    An issue during parsing of DNS responses allows a hostile DNS server to misuse memcpy, which leads to a read operation past an allocated buffer.

For Debian 8 Jessie, these problems have been fixed in version 5.6.40+dfsg-0+deb8u2.

We recommend that you upgrade your php5 packages.
