Severity: High
Title: Pavuk: Remote buffer overflow
Date: June 30, 2004
ID: 200406-22
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
