Title:	Vilistextum: Buffer overflow vulnerability
Date:	01/06/2005
Bugs:	#74694
ID:	200501-10

Synopsis

Vilistextum is vulnerable to a buffer overflow that allows an attacker to execute arbitrary code through the use of a malicious webpage.

Background

Vilistextum is an HTML to text converter.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-text/vilistextum	< 2.6.7	>= 2.6.7	All supported architectures

Description

Ariel Berkman discovered that Vilistextum unsafely reads data into an array without checking the length. This code vulnerability may lead to a buffer overflow.

Impact

A remote attacker could craft a malicious webpage which, when converted, would result in the execution of arbitrary code with the rights of the user running Vilistextum.

Workaround

There is no known workaround at this time.

Resolution

All Vilistextum users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/vilistextum-2.6.7"
