Debian 3.1: DSA 956-1 Critical: lsh-utils File Descriptor Leak Threat

Ubuntu released a security update for openssh addressing a critical vulnerability related to memory corruption in SSH clients.
Stefan Pfetzing discovered that lshd, a Secure Shell v2 (SSH2) protocol server, leaks a couple of file descriptors, related to the randomness generator, to user shells which are ...

Summary


For security reasons, lsh-make-seed really needs to be run from the
console of the system you are running it on. If you run lsh-make-seed
using a remote shell, the timing information lsh-make-seed uses for
its random seed creation is likely to be screwed. If need be, you can
generate the random seed on a different system than that which it will
eventually be on, by installing the lsh-utils package and running
"lsh-make-seed -o my-other-server-seed-file". You may then transfer
the seed to the destination system as using a secure connection.

The old stable distribution (woody) may not be affected by this problem.

For the stable distribution (sarge) this problem has been fixed in
version 2.0.1-3sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 2.0.1cdbs-4.

We recommend that you upgrade your lsh-server package.
