Fedora 20 : openssh-6.4p1-4.fc20 (2014-6380)
medium Nessus Plugin ID 74133
Language:
Synopsis
The remote Fedora host is missing a security update.Description
- environment variables with embedded '=' or '\0' characters are now ignored- prevents a server from skipping SSHFP lookup and forcing a new-hostkey dialog by offering only certificate keys
- ssh-agent is now suspend-aware as it gets also CLOCK_BOOTTIME time
- /etc/ssh/moduli is readable by all now
- sshd-keygen.service depends on existence of /etc/ssh/ssh_host_ecdsa_key instead of /etc/ssh/ssh_host_dsa_key by default
- ssh-copy-id is run in so called legacy mode when SSH_COPY_ID_LEGACY variable is set
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
