Background ========= Links is a web browser running in both graphics and text modes. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/links < 2.1_pre26 > = 2.1_pre26 Description ========== Teemu Salmela discovered that Links does not properly validate "smb://" URLs when it runs smbclient commands. 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 the 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 Links users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =www-client/links-2.1_pre26" References ========= [ 1 ] CVE-2006-5925 https://www.cve.org/CVERecord?id=CVE-2006-5925 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200612-16 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.
