Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2005-3120.

Yderligere oplysninger:

Ulf Härnhammar har opdaget et bufferoverløb inlynx, en tekstbaseret browser til WWW, som kunne fjernudnyttes. Under håndteringen af asiatiske tegn ved forbindelse til en NNTP-server, kunne lynx narres til at skrive ud over en buffers grænser, hvilket kunne medføre udførelse af vilkårlig kode.

I den gamle stabile distribution (woody) er dette problem rettet i version 2.8.4.1b-3.3.

I den stabile distribution (sarge) er dette problem rettet i version 2.8.5-2sarge1.

I den ustabile distribution (sid) vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer din lynx-pakke.
