Package: iputils-tracepath Version: 3:20180629-2+deb10u1 Severity: important File: /usr/bin/tracepath Tags: ipv6
The iputils-tracepath version currently packaged contains a bug, which results in ipv6 destination addresses being cut off after the first 64 bits. Because tracepath is trying to reach a different address than given by the user, tracepath is almost always unable to reach the destination host. For example, if the user tries to 'tracepath 2001:db8::1234', the probes are actually sent to '2001:db8::'. The bug was introduced in version 20180629 and has already been fixed upstream [1], which is included in version 20190324. However, this bug is still present in the iputils package from debian stable. This fix should probably be backported into debian stable because tracepath shows "!H" (destination address unreachable) for almost every ipv6 address (except for those with a suffix containing only 0-bits).
