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.
