Synopsis

Pavuk contains a bug potentially allowing an attacker to run arbitrary code.

Background

Pavuk is web spider and website mirroring tool.

Affected packages

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.
