SynopsisThe remote Debian host is missing a security update.
DescriptionAris Adamantiadis of the libssh team discovered that libssh, an SSH2 protocol implementation used by many applications, did not generate sufficiently long Diffie-Hellman secrets.
This vulnerability could be exploited by an eavesdropper to decrypt and to intercept SSH sessions.
For the oldoldstable distribution (squeeze), this has been fixed in version 0.4.5-3+squeeze3.
For the oldstable (wheezy) and stable (jessie) distributions, this will be fixed soon.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected libssh package.
