TIN: Multiple buffer overflows — GLSA 200611-18

Multiple buffer overflows have been reported in TIN, possibly leading to the execution of arbitrary code.

Affected Packages

net-nntp/tin on all architectures
Affected versions < 1.8.2
Unaffected versions >= 1.8.2

Background

TIN is a threaded NNTP and spool based UseNet newsreader for a variety of platforms.

Description

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.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All TIN users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-nntp/tin-1.8.2"
