Berørte pakker:

ekg

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2008-4776.

Yderligere oplysninger:

Man har opdaget, at ekg, en Gadu Gadu-klient til konsollen, udførte utilstrækkelig fornuftighedskontrol af inddata i koden, der fortolker kontaktbeskrivelser, hvilket måske kunne medføre lammelsesangreb (denial of service).

I den stabile distribution (etch), er dette problem rettet i version 1:1.7~rc2-1etch2.

I den ustabile distribution (sid) og i den kommende stabile distribution (lenny), er dette problem rettet i version 1:1.8~rc1-2 af libgadu.

Vi anbefaler at du opgraderer din ekg-pakke.

Rettet i:

Debian GNU/Linux 4.0 (etch)
