Synopsis ========
GNU Gadu, CenterICQ, Kadu, EKG and libgadu are vulnerable to an integer overflow which could potentially lead to the execution of arbitrary code or a Denial of Service.
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.
