Finally Checkpoint changed the way how objects are stored with the R80 release. This release is only running management, wonder when the gateways will be available.
Installed this version in a VMware ESXi 5.5 environment with not problems, at the moment it is running with 3Gb of memory at that is not enough. The swap is already used for 35% and it is only running the Gaia portal, management – and log server no active connections from Smart Console users or logging from gateways.
Well-known cryptography professor Matthew Green has discovered a new SSL vulnarability.
Diffie-Hellman key exchange is a popular cryptographic algorithm that allows Internet protocols to agree on a shared key and negotiate a secure connection. It is fundamental to many protocols including HTTPS, SSH, IPsec, SMTPS, and protocols that rely on TLS.
We have uncovered several weaknesses in how Diffie-Hellman key exchange has been deployed:
Logjam (CVE-2015-4000) Attack against the TLS Protocol. The Logjam attack allows a man-in-the-middle attacker to downgrade vulnerable TLS connections to 512-bit export-grade cryptography. This allows the attacker to read and modify any data passed over the connection. The attack is reminiscent of the FREAK attack, but is due to a flaw in the TLS protocol rather than an implementation vulnerability, and attacks a Diffie-Hellman key exchange rather than an RSA key exchange. The attack affects any server that supports DHE_EXPORT ciphers, and affects all modern web browsers. 8.4% of the Top 1 Million domains were initially vulnerable.
Threats from state-level adversaries. Millions of HTTPS, SSH, and VPN servers all use the same prime numbers for Diffie-Hellman key exchange. Practitioners believed this was safe as long as new key exchange messages were generated for every connection. However, the first step in the number field sieve—the most efficient algorithm for breaking a Diffie-Hellman connection—is dependent only on this prime. After this first step, an attacker can quickly break individual connections.We carried out this computation against the most common 512-bit prime used for TLS and demonstrate that the Logjam attack can be used to downgrade connections to 80% of TLS servers supporting DHE_EXPORT. We further estimate that an academic team can break a 768-bit prime and that a nation-state can break a 1024-bit prime. Breaking the single, most common 1024-bit prime used by web servers would allow passive eavesdropping on connections to 18% of the Top 1 Million HTTPS domains. A second prime would allow passive decryption of connections to 66% of VPN servers and 26% of SSH servers. A close reading of published NSA leaks shows that the agency’s attacks on VPNs are consistent with having achieved such a break.
CVE-2015-3456, is a security vulnerability in the virtual floppy drive code used by many computer virtualization platforms. This vulnerability may allow an attacker to escape from the confines of an affected virtual machine (VM) guest and potentially obtain code-execution access to the host. Absent mitigation, this VM escape could open access to the host system and all other VMs running on that host, potentially giving adversaries significant elevated access to the host’s local network and adjacent systems.
Exploitation of the VENOM vulnerability can expose access to corporate intellectual property (IP), in addition to sensitive and personally identifiable information (PII), potentially impacting the thousands of organizations and millions of end users that rely on affected VMs for the allocation of shared computing resources, as well as connectivity, storage, security, and privacy.
What products are affected:
The bug is in QEMU’s virtual Floppy Disk Controller (FDC). This vulnerable FDC code is used in numerous virtualization platforms and appliances, notably Xen, KVM, and the native QEMU client.
VMware, Microsoft Hyper-V, and Bochs hypervisors are not impacted by this vulnerability.
Since the VENOM vulnerability exists in the hypervisor’s codebase, the vulnerability is agnostic of the host operating system (Linux, Windows, Mac OS, etc.).
Though the VENOM vulnerability is also agnostic of the guest operating system, an attacker (or an attacker’s malware) would need to have administrative or root privileges in the guest operating system in order to exploit VENOM.
