Gentoo Linux Security Advisory

Title: Weex: Format string vulnerability (GLSA 200510-09)
Severity: normal
Exploitable: remote
Date: October 08, 2005
Bug(s): #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: net-ftp/weex
Vulnerable: < 2.6.1.5-r1
Unaffected: >= 2.6.1.5-r1
Architectures: 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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-ftp/weex-2.6.1.5-r1"
