In January, a zero-day vulnerability was found in all versions of Java 7, including the latest version Java 7 Update 10, which was already exploited in the wild. [9] The vulnerability was caused by a patch to fix an earlier vulnerability. [10] In response, Apple blacklisted the latest version of the Java plugin. [11]
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.
In February 2024, a malicious backdoor was introduced to the Linux build of the xz utility within the liblzma library in versions 5.6.0 and 5.6.1 by an account using the name "Jia Tan". [ b ] [ 4 ] The backdoor gives an attacker who possesses a specific Ed448 private key remote code execution capabilities on the affected Linux system.
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.
Some programs allow the conversion of Java programs from one version of the Java platform to an older one (for example Java 5.0 backported to 1.4) (see Java backporting tools). Regarding Oracle's Java SE support roadmap, [ 4 ] Java SE 23 is the latest version, while versions 21, 17, 11 and 8 are the currently supported long-term support (LTS ...
The feature causing the vulnerability could be disabled with a configuration setting, which had been removed [51] in Log4j version 2.15.0-rc1 (officially released on December 6, 2021, three days before the vulnerability was published), and replaced by various settings restricting remote lookups, thereby mitigating the vulnerability.
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.
