Debian Security Advisory

DLA-927-1 fop -- LTS security update

Date Reported:

29 Apr 2017

Affected Packages:

fop

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 860567.
In Mitre's CVE dictionary: CVE-2017-5661.

More information:

In Apache FOP before 2.2, files lying on the filesystem of the server which uses FOP can be revealed to arbitrary users who send maliciously formed SVG files. The file types that can be shown depend on the user context in which the exploitable application is running. If the user is root a full compromise of the server - including confidential or sensitive files - would be possible. XXE can also be used to attack the availability of the server via denial of service as the references within a xml document can trivially trigger an amplification attack.

For Debian 7 Wheezy, these problems have been fixed in version 1:1.0.dfsg2-6+deb7u1.

We recommend that you upgrade your fop packages.
