http://security.gentoo.org/

Severity:	normal
Title:	Weex: Format string vulnerability
Date:	10/08/2005
Bugs:	#107849
ID:	200510-09

Synopsis

Weex contains a format string error that may be exploited by malicious servers to execute arbitrary code.

Background

Weex is a non-interactive FTP client typically used to update web pages.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-ftp/weex	< 2.6.1.5-r1	>= 2.6.1.5-r1	All supported architectures

Description

Ulf Harnhammar discovered a format string bug in Weex that can be triggered when it is first run (or when its cache files are rebuilt, using the -r option).

Impact

An attacker could setup a malicious FTP server which, when accessed using Weex, could trigger the format string bug and end up executing arbitrary code with the rights of the user running Weex.

Workaround

There is no known workaround at this time.

Resolution

All Weex users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-ftp/weex-2.6.1.5-r1"
