Synopsis
========
A buffer overflow in TMSNC might lead to the execution of arbitrary
code when processing an instant message.
Background
==========
TMSNC is a Textbased client for the MSN instant messaging protocol.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-im/tmsnc <= 0.3.2-r1 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
Description
===========
Nico Golde reported a stack-based buffer overflow when processing a MSN
packet with a UBX command containing a large UBX payload length field.
Impact
======
A remote attacker could send a specially crafted message, possibly
resulting in the execution of arbitrary code.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
Since TMSNC is no longer maintained, we recommend that users unmerge
the vulnerable package and switch to another console-based MSN client
such as CenterIM or Pebrot:
# emerge --unmerge "net-im/tmsnc"
References
