Background ========== Weex is a non-interactive FTP client typically used to update web pages. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-ftp/weex < 2.6.1.5-r1 >= 2.6.1.5-r1 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" References ========== [ 1 ] CAN-2005-3150 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-3150 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200510-09.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
