[ASA-201705-19] fop: xml external entity injection
Arch Linux Security Advisory ASA-201705-19 ========================================== Severity: Medium Date : 2017-05-21 CVE-ID : CVE-2017-5661 Package : fop Type : xml external entity injection Remote : Yes Link : https://security.archlinux.org/AVG-254 Summary ======= The package fop before version 2.2-1 is vulnerable to xml external entity injection. Resolution ========== Upgrade to 2.2-1. # pacman -Syu "fop>=2.2-1" The problem has been fixed upstream in version 2.2. Workaround ========== None. Description =========== Files lying on the filesystem of the server which uses batik 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. Impact ====== A remote attacker is able to access files lying on the filesystem or crash the server via sending maliciously crafted SVG files.
