Log4Shell (CVE-2021-44228) is a zero-day vulnerability in Log4j, a popular Java logging framework, involving arbitrary code execution. The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021.
For example, in 2011, Oracle issued a security fix for a bug in the Double.parseDouble method. This method converts a string such as "12.34" into the equivalent double-precision floating point number. The bug caused this method to enter an infinite loop when called on a specific input. This bug had security implications, because for example if ...
A Java logging framework is a computer data logging package for the Java platform. This article covers general purpose logging frameworks. This article covers general purpose logging frameworks. Logging refers to the recording of activity by an application and is a common issue for development teams.
Apache License 2.0. Website. logging .apache .org /log4j /2 .x /. Apache Log4j is a Java -based logging utility originally written by Ceki Gülcü. It is part of the Apache Logging Services, a project of the Apache Software Foundation. Log4j is one of several Java logging frameworks . Gülcü has since created SLF4J, Reload4j, [4] and Logback ...
www .slf4j .org. Simple Logging Facade for Java ( SLF4J) provides a Java logging API by means of a simple facade pattern. The underlying logging backend is determined at runtime by adding the desired binding to the classpath and may be the standard Sun Java logging package java.util.logging, [2] Log4j, Reload4j, Logback [3] or tinylog.

Discrete logarithm. In mathematics, for given real numbers a and b, the logarithm log b a is a number x such that bx = a. Analogously, in any group G, powers bk can be defined for all integers k, and the discrete logarithm log b a is an integer k such that bk = a. In number theory, the more commonly used term is index: we can write x = ind r a ...
Origin. The register width of a processor determines the range of values that can be represented in its registers. Though the vast majority of computers can perform multiple-precision arithmetic on operands in memory, allowing numbers to be arbitrarily long and overflow to be avoided, the register width limits the sizes of numbers that can be operated on (e.g., added or subtracted) using a ...
In computing, the Java Cryptography Architecture ( JCA) is a framework for working with cryptography using the Java programming language. It forms part of the Java security API, and was first introduced in JDK 1.1 in the java.security package. The JCA uses a "provider"-based architecture and contains a set of APIs for various purposes, such as ...
