Package : libproxy-mozjs
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-1226
Summary
=======
The package libproxy-mozjs before version 0.4.16-1 is vulnerable to
denial of service.
Resolution

Upgrade to 0.4.16-1.
# pacman -Syu "libproxy-mozjs>=0.4.16-1"
The problem has been fixed upstream in version 0.4.16.
Workaround

Description
===========
url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a
remote HTTP PAC server to trigger uncontrolled recursion via a response
composed of an infinite stream that lacks a newline character. This
leads to stack exhaustion.
Impact

A remote HTTP PAC server might be able to crash an application via a
crafted response.
