Package        : spip
CVE ID         : CVE-2017-9736
Debian Bug     : 864921

Emeric Boit of ANSSI reported that SPIP, a website engine for
publishing, insufficiently sanitises the value from the X-Forwarded-Host
HTTP header field. An unauthenticated attacker can take advantage of
this flaw to cause remote code execution.

For the stable distribution (stretch), this problem has been fixed in
version 3.1.4-3~deb9u1.

For the testing distribution (buster), this problem has been fixed
in version 3.1.4-3.

For the unstable distribution (sid), this problem has been fixed in
version 3.1.4-3.

We recommend that you upgrade your spip packages.
