Detail

It has been discovered that in barnowl, a curses-based instant-messaging client, the return codes of calls to the ZPending and ZReceiveNotice functions in libzephyr were not checked, allowing attackers to cause a denial of service (crash of the application), and possibly execute arbitrary code.

For the stable distribution (lenny), this problem has been fixed in version 1.0.1-4+lenny2.

For the testing distribution (squeeze), this problem has been fixed in version 1.6.2-1.

For the unstable distribution (sid), this problem has been fixed in version 1.6.2-1.

We recommend that you upgrade your barnowl packages.
