Debian DSA-2102-1 : barnowl - unchecked return value

high Nessus Plugin ID 49103

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the barnowl packages.

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