Package        : barnowl
Vulnerability  : buffer overflow
Problem type   : remote
Debian-specific: no
CVE Id         : CVE-2010-0793
Debian Bug     : 574418

It has been discovered that barnowl, a curses-based tty Jabber, IRC, AIM
and Zephyr client, is prone to a buffer overflow via its "CC:" handling,
which could lead to the execution of arbitrary code.


For the stable distribution (lenny), this problem has been fixed in
version 1.0.1-4+lenny1.

For the testing distribution (squeeze) and the unstable distribution
(sid), this problem has been fixed in version 1.5.1-1.


We recommend that you upgrade your barnowl packages.
