All supported architectures
A buffer overflow in TMSNC might lead to the execution of arbitrary code
when processing an instant message.
TMSNC is a Textbased client for the MSN instant messaging protocol.
Nico Golde reported a stack-based buffer overflow when processing a MSN
packet with a UBX command containing a large UBX payload length field.
A remote attacker could send a specially crafted message, possibly
resulting in the execution of arbitrary code.
There is no known workaround at this time.
Since TMSNC is no longer maintained, we recommend that users unmerge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:
Code Listing 3.1: Resolution
# emerge --unmerge "net-im/tmsnc"
