FreeBSD : mbed TLS -- plaintext recovery vulnerabilities (f4876dd4-9ca8-11e8-aa17-0011d823eebd)
Simon Butcher reports : - When using a CBC based ciphersuite, a remote attacker can partially recover the plaintext. - When using a CBC based ciphersuite, an attacker with the ability to execute arbitrary code on the machine under attack can partially recover the plaintext by use of cache based...
hw: cpu: speculative store bypass
An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions a commonly used performance optimization. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the...

Bluetooth® pairing vulnerability
Summary: Bluetooth Pairing update. Description: 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®...
Security Bulletin: Malformed message headers could cause message transmission to be blocked through channels resulting in denial of service in IBM MQ(CVE-2018-1503)
Summary IBM MQ RCVR or CLUSRCVR type channels could go into retry status after receiving messages containing invalid or malformed headers. This results in blocking of further transmission of messages. Vulnerability Details CVEID: CVE-2018-1503 DESCRIPTION: IBM MQ could allow a remotely...

Design/Logic Flaw
Android devices with code from Ragentek contain a privileged binary that performs over-the-air OTA update checks. Additionally, there are multiple techniques used to hide the execution of this binary. This behavior could be described as a rootkit. This binary, which resides as /system/bin/debugs,...
DEBIAN-CVE-2018-14044
The RateTransposer::setChannels function in RateTransposer.cpp in libSoundTouch.a in Olli Parviainen SoundTouch 2.0 allows remote attackers to cause a denial of service assertion failure and application exit, as demonstrated by SoundStretch...
Fresh Spectre Variants Come to Light
Two new speculative execution bugs have earned researchers a $100,000 bug bounty from Intel. MIT’s Vladimir Kiriansky and independent researcher Carl Waldspurger uncovered what they call Spectre1.1 and a subset, Spectre1.2, collectively referred to as Variant 4 of Spectre by Intel and ARM. Like t...
Computerinsel Photoline PSD Blending Channel Code Execution Vulnerability
Summary A memory corruption vulnerability exists in the PSD-parsing functionality of Computerinsel Photoline 20.54. A specially crafted PSD image processed via the application can lead to a stack overflow, overwriting arbitrary data. An attacker can deliver a PSD image to trigger this vulnerabili...

Kernel: FPU state information leakage via lazy FPU restore
A Floating Point Unit FPU state information leakage flaw was found in the way the Linux kernel saved and restored the FPU state during task switch. Linux kernels that follow the "Lazy FPU Restore" scheme are vulnerable to the FPU state information leakage issue. An unprivileged local attacker cou...
