Multiple integer overflows in libgadu, as used in Kopete in KDE 3.2.3 to 3.4.1, ekg before 1.6rc3, GNU Gadu, CenterICQ, Kadu, and other packages, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an incoming message.
Certain contributed scripts for ekg Gadu Gadu client 1.5 and earlier create temporary files insecurely, with unknown impact and attack vectors, a different vulnerability than CVE-2005-1916.
