Synopsis ========
Multiple vulnerabilities have been found in OpenSSH, the worst of which could allow a remote attacker to execute arbitrary code.
Background ==========
OpenSSH is a complete SSH protocol implementation that includes SFTP client and server support.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/openssh < 8.5_p1 >= 8.5_p1
Description ===========
Multiple vulnerabilities have been discovered in OpenSSH. Please review the CVE identifiers referenced below for details.
Impact ======
A remote attacker, able to access the socket of the forwarding agent, might be able to execute arbitrary code with the privileges of the process or cause a Denial of Service condition. Furthermore, a remote attacker might conduct a man-in-the-middle attack targeting initial connection attempts where no host key for the server has been cached by client yet.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All OpenSSH users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/openssh-8.5_p1"
