All versions of Node.js 8.x, 9.x, and 10.x are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node server providing an http2 server to crash. This can be accomplished by interacting with the http2 server in a manner that triggers a cleanup bug where objects are used in native code after they are no longer available. This has been addressed by updating the http2 implementation.
In January, 2018, Microsoft published an advisory and security updates for a new class of hardware vulnerabilities involving speculative execution side channels (known as Spectre and Meltdown). In this blog post, we will provide a technical analysis of an additional subclass of speculative execution side channel vulnerability known as Speculative Store Bypass (SSB) which has been assigned CVE-2018-3639.
Adobe Flash Player versions 28.0.0.161 and earlier have an exploitable use after free vulnerability. Successful exploitation could lead to arbitrary code execution in the context of the current user.
Adobe Flash Player versions 29.0.0.113 and earlier have an exploitable out-of-bounds read vulnerability. Successful exploitation could lead to information disclosure.
The Node.js inspector, in 6.x and later is vulnerable to a DNS rebinding attack which could be exploited to perform remote code execution. An attack is possible from malicious websites open in a web browser on the same computer, or another computer with network access to the computer running the Node.js process. A malicious website could use a DNS rebinding attack to trick the web browser to bypass same-origin-policy checks and to allow HTTP connections to localhost or to hosts on the local network. If a Node.js process with the debug port active is running on localhost or on a host on the local network, the malicious website could connect to it as a debugger, and get full code execution access.
An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * hw: cpu: speculative execution permission faults handling (CVE-2017-5754, x86 32-bit) * Kernel: error in exception handling leads to DoS (CVE-2018-8897) * kernel: nfsd: Incorrect handling of long RPC replies (CVE-2017-7645) * kernel: Use-after-free vulnerability in DCCP socket (CVE-2017-8824) * kernel: v4l2: disabled memory access protection mechanism allowing privilege escalation (CVE-2017-13166) * kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c (CVE-2017-18017) * kernel: Stack information leak in the...
Stack-based buffer overflow in the get_key function in parse.c in abcm2ps through 8.13.20 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
Stack-based buffer overflow in the delayed_output function in music.c in abcm2ps through 8.13.20 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
An update for kernel is now available for Red Hat Enterprise Linux 5.9 Long Life. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation i...
