Description

Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 update 4 and earlier, 6 update 32 and earlier, 5 update 35 and earlier, and 1.4.2_37 and earlier allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Hotspot.

In plain language

AI Act now

This is a critical, remotely exploitable flaw in older Java Runtime Environments that can let an attacker take over the machine or disrupt services without login—if your business still runs those Java versions, you should act now.

Executive summary

CVE-2012-1723 is a Hotspot component vulnerability in affected Oracle Java Runtime Environments that allows an unauthenticated remote attacker (network-accessible, no user interaction) to compromise confidentiality, integrity, and availability.

What to do now

  1. Check whether any systems in your business run an affected Java Runtime Environment (Oracle Java SE 7 update 4 or earlier, 6 update 32 or earlier, 5 update 35 or earlier, or 1.4.2_37 or earlier).
  2. If you run icedtea6, upgrade it to version 1.10.8 or later.
  3. If you run Oracle Java SE, replace/upgrade the JRE to a vendor-recommended fixed update (follow Oracle’s Java security update guidance for your exact Java line).
  4. After upgrading, re-scan and confirm the vulnerable Java versions are no longer installed and no old Java packages remain in use.
sudo apt-get update && sudo apt-get install icedtea6=1.10.8*
