Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
Speculative Store Bypass (SSB) (CVE-2018-3639) is the name given to a hardware security vulnerability and its exploitation that takes advantage of speculative execution in a similar way to the Meltdown and Spectre security vulnerabilities. [1] It affects the ARM, AMD and Intel families of processors.
The kernel connects the application software to the hardware of a computer. Kernel Patch Protection (KPP), informally known as PatchGuard, is a feature of 64-bit editions of Microsoft Windows that prevents patching the kernel. It was first introduced in 2005 with the x64 editions of Windows Vista and Windows Server 2003 Service Pack 1. [1]
Since the disclosure of Spectre and Meltdown in January 2018, much research had been done on vulnerabilities related to speculative execution. On 3 May 2018, eight additional Spectre-class flaws provisionally named Spectre-NG by c't (a German computer magazine) were reported affecting Intel and possibly AMD and ARM processors. Intel reported ...
Metasploit was created by H. D. Moore in 2003 as a portable network tool using Perl.By 2007, the Metasploit Framework had been completely rewritten in Ruby.On October 21, 2009, the Metasploit Project announced [4] that it had been acquired by Rapid7, a security company that provides unified vulnerability management solutions.
Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...
It was a high-volume mailing list, with as many as 776 posts in a month, [1] and almost all new security vulnerabilities were discussed on the list in its early days. The forum provided a vehicle for anyone to disclose and discuss computer vulnerabilities , including security researchers and product vendors.
Full Disclosure is a "lightly moderated" security mailing list generally used for discussion about information security and disclosure of vulnerabilities. The list was created on July 9, 2002, by Len Rose and also administered by him, who later handed it off to John Cartwright.
