SCA: security update for com.github.junrar:junrar (GHSA-h9h9-2rmf-rvhp)

high Tenable Cloud Security Plugin ID 474727

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Junrar is an open source Java RAR archive library. Prior to 7.6.1, RarVM.ExecuteCode in
 src/main/java/com/github/junrar/unpack/vm/RarVM.java can repeatedly execute a VM_JMP instruction whose
 target is greater than or equal to the prepared program's codeSize. The setIP() function returns success
 without changing the instruction pointer or decrementing maxOpCount, and the jump handler continues before
 loop-end accounting, leaving both values unchanged. A crafted RAR4 archive can therefore keep an
 extraction thread in an infinite CPU loop and exhaust archive-processing worker capacity. The RAR virtual
 machine does not expose native process execution, so the supported impact is availability loss rather than
 code execution. This issue is fixed in version 7.6.1. (CVE-2026-97370)

Solution

Update the com.github.junrar:junrar library and its related packages to version 7.6.1 or later.
