Vulnerabilities in native libraries, such as the C standard library, which may be used to implement the application and/or runtime; Vulnerabilities caused purely by errors in user programs (for example improper construction of SQL queries leading to SQL injection vulnerabilities) However, much discussion of Java security focusses on potential ...
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.
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
Memory errors were first considered in the context of resource management (computing) and time-sharing systems, in an effort to avoid problems such as fork bombs. [4] Developments were mostly theoretical until the Morris worm , which exploited a buffer overflow in fingerd . [ 5 ]
A software bug is a design defect in computer software.A computer program with many or serious bugs may be described as buggy.. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing).
When a dangling pointer is used after it has been freed without allocating a new chunk of memory to it, this becomes known as a "use after free" vulnerability. [4] For example, CVE - 2014-1776 is a use-after-free vulnerability in Microsoft Internet Explorer 6 through 11 [ 5 ] being used by zero-day attacks by an advanced persistent threat .
