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.
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.
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.
This type of vulnerability would be bad enough if it was limited to just one product or brand. But because Log4j is such a ubiquitous technology, the effect of this will be exponentially higher.
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]
Successful exploitation of a code injection vulnerability can result in data breaches, access to restricted or critical computer systems, and the spread of malware. Code injection vulnerabilities occur when an application sends untrusted data to an interpreter, which then executes the injected text as
Many other programming languages, such as Java, do not automatically prevent memory-based race conditions, yet are still generally considered "memory safe" languages. Therefore, countering race conditions is generally not considered necessary for a language to be considered memory safe.
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 ...
