Background ========== ELinks is a text mode web browser. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/elinks < 0.11.2 >= 0.11.2 Description =========== Teemu Salmela discovered an error in the validation code of "smb://" URLs used by ELinks, the same issue as reported in GLSA 200612-16 concerning Links. Impact ====== A remote attacker could entice a user to browse to a specially crafted "smb://" URL and execute arbitrary Samba commands, which would allow the overwriting of arbitrary local files or the upload or download of arbitrary files. This vulnerability can be exploited only if "smbclient" is installed on the victim's computer, which is provided by the "samba" Gentoo package. Workaround ========== There is no known workaround at this time. Resolution ========== All ELinks users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/elinks-0.11.2" References ========== [ 1 ] CVE-2006-5925 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5925 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200701-27.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. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
