This issue is fixed in the current version of ClearOS but may show up as a false positive for systems which scan version numbers. ClearOS backports fixes into prior version numbers in order to provide longevity and interoperability in its software. If the system is up to date, this backport fix has been applied in the following versions:

  • openssh-5.3p1-104.el6.x86_64.rpm
  • openssh-clients-5.3p1-104.el6.x86_64.rpm
  • openssh-debuginfo-5.3p1-104.el6.i686.rpm

  • openssh-server-5.3p1-104.el6.x86_64.rpm

  • pam_ssh_agent_auth-0.9.3-104.el6.x86_64.rpm

To confirm your running version to ensure that it is a later version run the following from command line:

rpm -qi openssh

This will tell you the result of the first package affected and fixed in ClearOS. You can apply the methodology to the other packages. For example:

rpm -qi openssh-server

Resolution

yum update

Once the system is up to date, answer to those reporting this issue that the fixes have been backported into the existing version number.
