Background ========== Newspost is a Usenet News binary autoposter. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-nntp/newspost < 2.0-r1 >= 2.0-r1 Description =========== Niels Heinen has discovered a buffer overflow in the socket_getline() function of Newspost, which can be triggered by providing long strings that do not end with a newline character. Impact ====== A remote attacker could setup a malicious NNTP server and entice a Newspost user to post to it, leading to the crash of the Newspost process and potentially the execution of arbitrary code with the rights of the Newspost user. Workaround ========== There is no known workaround at this time. Resolution ========== All Newspost users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-nttp/newspost-2.0-r1" References ========== [ 1 ] CAN-2005-0101 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0101 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200502-05.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.
