|Gentoo Linux Security Advisory
Title: TMSNC: Execution of arbitrary code (GLSA 200903-26)
Date: March 12, 2009
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.
Vulnerable: <= 0.3.2-r1
Architectures: All supported architectures
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Since TMSNC is no longer maintained, we recommend that users unmerge the vulnerable package and switch to another console-based MSN client such as CenterIM or Pebrot:
|# emerge --unmerge "net-im/tmsnc" |
