Background ========== noip-updater is a tool used for updating IP addresses of dynamic DNS records at no-ip.com. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dns/noip-updater < 2.1.9 >= 2.1.9 Description =========== xenomuta found out that the GetNextLine() function in noip2.c misses a length check, leading to a stack-based buffer overflow. Impact ====== A remote attacker could exploit this vulnerability to execute arbitrary code by sending a specially crafted HTTP message to the client. NOTE: Successful exploitation requires a man in the middle attack, a DNS spoofing attack or a compromise of no-ip.com servers. Workaround ========== There is no known workaround at this time. Resolution ========== All noip-updater users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-dns/noip-updater-2.1.9" References ========== [ 1 ] CVE-2008-5297 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5297 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200901-12.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.
