Synopsis
========
Pavuk contains a bug potentially allowing an attacker to run arbitrary
code.
Background
==========
Pavuk is web spider and website mirroring tool.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/pavuk <= 0.9.28-r1 >= 0.9.28-r2
Description
===========
When Pavuk connects to a web server and the server sends back the HTTP
status code 305 (Use Proxy), Pavuk copies data from the HTTP Location
header in an unsafe manner.
Impact
======
An attacker could cause a stack-based buffer overflow which could lead
to arbitrary code execution with the rights of the user running Pavuk.
Workaround
==========
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version.
Resolution
==========
All Pavuk users should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=net-misc/pavuk-0.9.28-r2"
# emerge ">="net-misc/pavuk-0.9.28-r2
