Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All TIN users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dnet-nntp/tin-1.8.2"
