Date:	11/24/2006
Bugs:	#150229
ID:	200611-18

Synopsis

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

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-nntp/tin	< 1.8.2	>= 1.8.2	All supported architectures

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"
