[ Juniper ] Information Disclosure Vulnerability in OpenSSL (Heartbleed)


The TLS and DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information (such as private keys, username and passwords, or contents of encrypted traffic) from process memory via crafted packets that trigger a buffer over-read. This issue is also known as “The Heartbleed Bug”.

This Bug impact is rated HIGH Status of different OpenSSL versions:
  • OpenSSL 1.0.1 through 1.0.1f (inclusive) are vulnerable
  • OpenSSL 1.0.1g is NOT vulnerable
  • OpenSSL 1.0.0 branch is NOT vulnerable
  • OpenSSL 0.9.8 branch is NOT vulnerable

Temporary Workaround (before OS UPGRADE)
  • Since SSL is used for remote network configuration and management applications such as J-Web and SSL Service for JUNOScript (XNM-SSL), viable workarounds for this issue in Junos may include:
    • Disabling J-Web
    • Disable SSL service for JUNOScript and only use Netconf, which makes use of SSH, to make configuration changes Limit access to J-Web and XNM-SSL from only trusted networks
SSL VPN/UAC: Other than upgrading/downgrading to an unaffected release, there are no workarounds for this issue. Immediate action required to verify all internet facing servers are patched and also ensure all Perimeter security services are using updated HeartBleed signatures to detect and prevent abusing the vulnerability for internal and external threats.

NEW BUG UNCOVERED – a vulnerability which exists in OpenSSL has recently been uncovered. The vulnerability is an information disclosure bug which is due to an error when handling TLS/DTLS heartbeat packets. An attacker can leverage this vulnerability to disclose memory contents of a connected client or server.
