Ubuntu 18.04 LTS : Linux kernel vulnerabilities (USN-4208-1)

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4208-1 advisory. Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux kernel did not properly handle reference counting during memory mapping operatio...

Code injection

Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate attackers to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the electromagnetic field during...

USN-4115-2: Linux kernel regression

USN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update, a regression was introduced that caused a kernel crash when handling fragmented packets in some situations. This update addresses the issue. We apologize for...

The Fully Remote Attack Surface of the iPhone

Posted by Natalie Silvanovich, Project Zero While there have been several rumours and reports of fully remote vulnerabilities affecting the iPhone being used by attackers in the last couple of years, limited information is available about the technical details of these vulnerabilities, as well as...

kernel: Heap address information leak while using L2CAP_PARSE_CONF_RSP

A flaw was found in the Linux kernel's implementation of logical link control and adaptation protocol L2CAP, part of the Bluetooth stack in the l2capparseconfrsp and l2capparseconfreq functions. An attacker with physical access within the range of standard Bluetooth transmission can create a...

kernel: Bluetooth implementations may not sufficiently validate elliptic curve parameters during Diffie-Hellman key exchange

A vulnerability in Bluetooth pairing potentially allows an attacker with physical proximity within 30 meters to gain unauthorized access via an adjacent network, intercept traffic and send forged pairing messages between two vulnerable Bluetooth devices. This may result in information disclosure,...

Tap 'n Ghost Attack Creatively Targets Android Devices

Researchers have created a novel proof-of-concept PoC attack named Tap ‘n Ghost, which targets Near Field Communication NFC-enabled Android smartphones. This allows an attacker to take control of a target phone simply by tricking the victim into placing their handset on a specially crafted surfac...
