CVE-2006-0582

Privilege escalation in the rsh server allows an authenticated attacker to overwrite arbitrary files and gain ownership of them.

CVE-2006-0677

A remote attacker could force the telnet server to crash before the user logged in, resulting in inetd turning telnetd off because it forked too fast.

The old stable distribution (woody) does not expose rsh and telnet servers.

For the stable distribution (sarge) these problems have been fixed in version 0.6.3-10sarge2.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your heimdal packages.");
