The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
Log4Shell (CVE-2021-44228) is a zero-day vulnerability reported in November 2021 in Log4j, a popular Java logging framework, involving arbitrary code execution. [2] [3] 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.
The Java programming language and Java software platform have been criticized for design choices including the implementation of generics, forced object-oriented programming, the handling of unsigned numbers, the implementation of floating-point arithmetic, and a history of security vulnerabilities in the primary Java VM implementation, HotSpot.
How bad is this vulnerability? The Log4j tool is so widely distributed across websites, networking, and other software that it is essentially a ubiquitous technology and a key part of the software ...
In C++, because dereferencing a null pointer is undefined behavior, compiler optimizations may cause other checks to be removed, leading to vulnerabilities elsewhere in the code. [ 29 ] [ 30 ] Some lists may also include race conditions (concurrent reads/writes to shared memory) as being part of memory safety (e.g., for access control).
Secure coding is the practice of developing computer software in such a way that guards against the accidental introduction of security vulnerabilities.Defects, bugs and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities. [1]
A zero-day vulnerability involving remote code execution in Log4j 2, given the descriptor "Log4Shell" (CVE-2021-44228), was found and reported to Apache by Alibaba on November 24, 2021, and published in a tweet on December 9, 2021. [12] Affected services include Cloudflare, iCloud, Minecraft: Java Edition, [42] Steam, Tencent QQ, and Twitter.
When integrated into a CI/CD context, SAST tools can be used to automatically stop the integration process if critical vulnerabilities are identified. [ 19 ] Because the tool scans the entire source-code, it can cover 100% of it, while dynamic application security testing covers its execution possibly missing part of the application, [ 6 ] or ...
