TIN is a threaded NNTP and spool based UseNet newsreader for a variety of platforms.
Urs Janssen and Aleksey Salow have reported multiple buffer overflows in TIN. Additionally, the OpenPKG project has reported an allocation off-by-one flaw which can lead to a buffer overflow.
An attacker could entice a TIN user to read a specially crafted news article, and execute arbitrary code with the rights of the user running TIN.
There is no known workaround at this time.
All TIN users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-nntp/tin-1.8.2"
