Yderligere oplysninger:

Edward Shornock har opdaget en fejl i UIDL-håndteringskoden i fetchmail, et udbredt posthentningsværktil til POP3, APOP og IMAP. En ondsindet POP3-server kunne udnytte dette problem ved at indsprøjte vilkårlig kode, der blev udført på offerets maskine. Hvis fetchmail kører som root, bliver dette til en root-udnyttelse.

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

I den stabile distribution (sarge) er dette problem rettet i version 6.2.5-12sarge1.

I den ustabile distribution (sid) er dette problem rettet i version 6.2.5-16.

Vi anbefaler at du opgraderer din fetchmail-pakke.

Rettet i:

Debian GNU/Linux 3.1 (sarge)
