These problems exist on IBM AIX 3.2.4 systems that have Program Temporary Fixes (PTFs) U420020 or U422510 installed and and on all AIX 3.2.5 systems. BACKGROUND: Vulnerabilities exist in the bosext1.extcmds.obj performance tools in AIX 3.2.5 and in those AIX 3.2.4 systems with Program Temporary Fixes (PTFs) U420020 or U422510 installed. These problems do not exist in earlier versions of AIX. IMPACT: Local users can gain unauthorized root access to the system. RECOMMENDED SOLUTION: A. The recommended temporary solution for this problem is to change the permissions of all the programs in the /usr/lpp/bosperf directory structure so that the setuid bit is removed and the programs can be executed only by 'root'. This can be accomplished as follows: % su root # chmod -R u-s,og= /usr/lpp/bosperf/* The programs affected by this workaround include: filemon, fileplace, genkex, genkld, genld, lvedit, netpmon, rmap, rmss, stripnm, svmon, tprof As a result of this workaround, these programs will no longer be executable by users other than 'root'. B. The recommended permanent solution for this problem is to order and install the patches contained in Authorized Program Analysis Report (APAR) IX42332. To order an APAR from IBM call 1-800-237-5511 and ask for shipment as soon as it is available. APARs may be obtained outside the U.S. by contacting your local IBM representative.
