Arch Linux Security Advisory ASA-201512-12
Date : 2015-12-17
CVE-ID : CVE-2015-8549
Package : python2-pyamf
Type : XML external entity injection
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE
The package python2-pyamf before version 0.8.0-2 is vulnerable to XML
external entity injection.
Upgrade to 0.8.0-2.
# pacman -Syu "python2-pyamf>=0.8.0-2"
The problem has been fixed upstream in version 0.8.0
PyAMF suffers from insufficient AMF input payload sanitization which
results in the XML parser not preventing the processing of XML external
A specially crafted AMF payload, containing malicious references to XML
external entities, can be used to trigger denial of service (DoS)
conditions or arbitrarily return the contents of files that are
accessible with the running application privileges.
A remote attacker is able to craft special XML files that, when
processed, are injecting external entities resulting in denial of
service of disclosure of arbitrary file contents.
