DescriptionThe remote host is affected by the vulnerability described in GLSA-200410-28 (rssh: Format string vulnerability)
Florian Schilhabel from the Gentoo Linux Security Audit Team found a format string vulnerability in rssh syslogging of failed commands.
Using a malicious command, it may be possible for a remote authenticated user to execute arbitrary code on the target machine with user rights, effectively bypassing any restriction of rssh.
There is no known workaround at this time.

# emerge --sync # emerge --ask --oneshot --verbose '>=app-shells/rssh-2.2.2'
