GNU Gadu, CenterICQ, Kadu and EKG are instant messaging applications created to support Gadu Gadu instant messaging protocol. libgadu is a library that implements the client side of the Gadu-Gadu protocol.

GNU Gadu, CenterICQ, Kadu, EKG and libgadu are vulnerable to an integer overflow.

A remote attacker could exploit the integer overflow to execute arbitrary code or cause a Denial of Service.

There is no known workaround at this time.

All GNU Gadu users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-im/gnugadu-2.2.6-r1"

All Kadu users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-im/kadu-0.4.1"

All EKG users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-im/ekg-1.6_rc3"

All libgadu users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-libs/libgadu-20050719"

All CenterICQ users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-im/centericq-4.20.0-r3"

CenterICQ is no longer distributed with Gadu Gadu support, affected users are encouraged to migrate to an alternative package.
