Package : barnowl
Vulnerability : unchecked return value
Problem type : remote
Debian-specific: no
CVE Id : CVE-2010-2725
Debian Bug : 593299
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.
