Fedora 40 2024-129d8ca6fc High Severity: Jflex Type Confusion Fixes

fedora
Calendar Grey March 7, 2024
Dist Fedora Esm H88
Fedora has released an update for JFlex to fix critical type confusion vulnerabilities, stressing the importance for developers to upgrade their JDK for improved security and stability
Change for system JDK from 17 to 21

Summary

JFlex is a lexical analyzer generator (also known as scanner

generator) for Java, written in Java. It is also a rewrite of the

very useful tool JLex which was developed by Elliot Berk at Princeton

University. As Vern Paxson states for his C/C++ tool flex: They do

not share any code though. JFlex is designed to work together with

the LALR parser generator CUP by Scott Hudson, and the Java

modification of Berkeley Yacc BYacc/J by Bob Jamison. It can also be

used together with other parser generators like ANTLR or as a

standalone tool.
