Synopsis ========
A buffer overflow can be exploited to crash Newspost remotely and potentially execute arbitrary code.
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"
