Arch Linux Security Advisory ASA-201502-1
========================================
Severity: Medium
Date    : 2015-02-03
CVE-ID  : CVE-2015-1380 CVE-2015-1381 CVE-2015-1382
Package : privoxy
Type    : denial of service
Remote  : Yes
Link    : https://wiki.archlinux.org/title/CVE

Summary
======
The package privoxy before version 3.0.23-1 is vulnerable to denial of
service.

Resolution
=========
Upgrade to 3.0.23-1.

# pacman -Syu "privoxy>=3.0.23-1"

The problems have been fixed upstream in version 3.0.23.

Workaround
=========
None.

Description
==========
- CVE-2015-1380 (denial of service)
Denial of service issue was found in case of client requests with
incorrect chunk-encoded body. When compiled with assertions enabled (the
default) they could previously cause Privoxy to abort().

- CVE-2015-1381 (segmentation fault)
Multiple segmentation faults and memory leaks were found in the pcrs
code. This fix also increases the chances that an invalid pcrs command
is rejected as such. Previously some invalid commands would be loaded
without error. Note that privoxy's pcrs sources (action and filter
files) are considered trustworthy input and should not be writable by
untrusted third-parties.

- CVE-2015-1382 (denial of service)
A 'invalid read' bug was found which could at least theoretically cause
privoxy to crash.

Impact
=====
A remote attacker is able to perform a denial of service attack via
crafted requests or a segmentation fault via invalid pcrs commands.
