Severity: Low Title: OpenSSH: Security bypass Date: November 01, 2007 Bugs: #191321 ID: 200711-02
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
========== 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"
