FIXES IBM strongly recommends addressing the vulnerability now. AIX and VIOS fixes are available and can be downloaded from Fix Central: https://www.ibm.com/support/fixcentral An LPAR reboot is required to complete the SP/FP update. On AIX, Live Update can be used to avoid a reboot. IBM has assigned the following AIX Service Packs (SPs) and VIOS Fix Packs (FPs) as the remediation levels for the published vulnerabilities. AIX Level Service PackAIX 7.3 TL04SP2AIX 7.3 TL03SP3AIX 7.3 TL02SP5AIX 7.2 TL05 SP13 PowerVM VIOS LevelFix PackVIOS 4.1.2 4.1.2.20VIOS 4.1.1 4.1.1.30VIOS 4.1.0 4.1.0.50 Note: These SPs/FPs are cumulative and include fixes for all previously published AIX/VIOS security vulnerabilities. They can be applied on top of any earlier affected level of the TL . Note: To apply these patches using nimsh secure, special steps must be taken as the protocol between master and client is updated to be more secure. Please read this article: https://www.ibm.com/support/pages/node/7283157 Note: For VIOS 4.1.0 and VIOS 4.1.1, additional steps are required to migrate to the latest Postgres15 after applying the 4.1.1.30 or 4.1.0.50 FPs above. Instructions to do that can be found here: 4.1.0.50 post-update instructions: https://www.ibm.com/support/pages/node/7283819 4.1.1.30 post-update instructions: https://www.ibm.com/support/pages/node/7283823
