Memory leak in the image message functionality in ekg before 1:1.7~rc2-1etch1 on Debian GNU/Linux Etch allows remote attackers to cause a denial of service.

ekg before 1:1.7~rc2-1etch1 on Debian GNU/Linux Etch allows remote attackers to cause a denial of service (NULL pointer dereference) via a vector related to the token OCR functionality.

Memory leak in the token OCR functionality in ekg before 1:1.7~rc2-1etch1 on Debian GNU/Linux Etch allows remote attackers to cause a denial of service.

security flaw

Multiple integer signedness errors in libgadu, as used in ekg before 1.6rc2 and other packages, may allow remote attackers to cause a denial of service or execute arbitrary code.

security flaw

Multiple "memory alignment errors" in libgadu, as used in ekg before 1.6rc2, Gaim before 1.5.0, and other packages, allows remote attackers to cause a denial of service (bus error) on certain architectures such as SPARC via an incoming message.

security flaw

Multiple "endianness errors" in libgadu in ekg before 1.6rc2 allow remote attackers to cause a denial of service (invalid behavior in applications) on big-endian systems.

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.

A certain contributed script for ekg Gadu Gadu client 1.5 and earlier allows attackers to execute shell commands via unknown attack vectors.

security flaw

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.

EKG Gadu 1.9 Local Buffer Overflow via Username Parameter

EKG Gadu 1.9~pre+r2855-3+b1 contains a local buffer overflow vulnerability in the username handling that allows local attackers to execute arbitrary code by supplying an oversized username string. Attackers can trigger the overflow in the strlcpy function by passing a crafted buffer exceeding 258 bytes to overwrite the instruction pointer and execute shellcode with user privileges.
