Synopsis ========
A flaw has been discovered in OpenSSH which could allow a local attacker to bypass security restrictions.
Background ==========
OpenSSH is a complete SSH protocol implementation that includes an SFTP client and server support.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/openssh < 4.7 >= 4.7
Description ===========
Jan Pechanec discovered that OpenSSH uses a trusted X11 cookie when it cannot create an untrusted one.
Impact ======
An attacker could bypass the SSH client security policy and gain privileges by causing an X client to be treated as trusted.
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-4.7"
References ==========
