"The 'send_email' function in
graphite-web/webapp/graphite/composer/views.py in Graphite is
vulnerable to SSRF. The vulnerable SSRF endpoint can be used by an
attacker to have the Graphite web server request any resource. The
response to this SSRF request is encoded into an image file and then
sent to an e-mail address that can be supplied by the attacker. Thus,
an attacker can exfiltrate any information.

For Debian 8 'Jessie', this problem has been fixed in version
0.9.12+debian-6+deb8u1.

We recommend that you upgrade your graphite-web packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
