Berørte pakker:

ppp

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2006-2194.

Yderligere oplysninger:

Marcus Meissner har opdaget at webbind-plugin'en i pppd ikke kontrollerer om et setuid()-kald har haft succes, når rettighedernes forsøges smidt væk, hvilket kunne fejle ved nogle PAM-opsætninger.

Den gamle stabile distribution (woody) er ikke påvirket af dette problem.

I den stabile distribution (sarge) er dette problem rettet i version 2.4.3-20050321+2sarge1.

I den ustabile distribution (sid) er dette problem rettet i version 2.4.4rel-1.

Vi anbefaler at du opgraderer din ppp-pakke.

Rettet i:

Debian GNU/Linux 3.1 (sarge)
