Background ========== 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. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-im/gnugadu < 2.2.6-r1 >= 2.2.6-r1 2 net-im/centericq < 4.20.0-r3 >= 4.20.0-r3 3 net-im/kadu < 0.4.1 >= 0.4.1 4 net-im/ekg < 1.6_rc3 >= 1.6_rc3 5 net-libs/libgadu < 20050719 >= 20050719 ------------------------------------------------------------------- 5 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== GNU Gadu, CenterICQ, Kadu, EKG and libgadu are vulnerable to an integer overflow. Impact ====== A remote attacker could exploit the integer overflow to execute arbitrary code or cause a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== 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.
