Vulnerabilities in the Java class library which an application relies upon for its security; A vulnerability in the Java platform will not necessarily make all Java applications vulnerable. When vulnerabilities and patches are announced, for example by Oracle, the announcement will normally contain a breakdown of which types of application are ...
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.
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]
Zero-day vulnerabilities are often classified as alive—meaning that there is no public knowledge of the vulnerability—and dead—the vulnerability has been disclosed, but not patched. If the software's maintainers are actively searching for vulnerabilities, it is a living vulnerability; such vulnerabilities in unmaintained software are ...
The weak-key-generation vulnerability was promptly patched after it was reported, but any services still using keys that were generated by the old code remain vulnerable. A number of software packages now contain checks against a weak key blacklist to attempt to prevent use of any of these remaining weak keys, but researchers continue to find ...
Vulnerabilities can be discovered with a vulnerability scanner, which analyzes a computer system in search of known vulnerabilities, [3] such as open ports, insecure software configurations, and susceptibility to malware infections. They may also be identified by consulting public sources, such as NVD, vendor specific security updates or ...
