Description:
Some vulnerabilities have been reported in IBM AIX, which can be exploited by malicious, local users to disclose potentially sensitive information, manipulate certain files, or gain escalated privileges.
1) A boundary error in the pioout command can be exploited to cause a buffer overflow and execute arbitrary code with root privileges.
2) An unspecified error in the ps command allows users to access potentially sensitive information from an arbitrary process.
The vulnerabilities are reported in versions 5.2.0, 5.3.0, 5.3.7, and 6.1.0.
3) Boundary errors in the uspchrp and utape commands can be exploited by users in the 'system' group to cause a buffer overflow and execute arbitrary code with root privileges.
The vulnerabilities are reported in versions 5.2.0, 5.3.0, and 5.3.7.
4) Boundary errors in the lchangevg, ldeletepv, putlvodm, lvaryoffvg, lvgenminor, swap, swapoff, and swapon commands can be exploited by users in the 'system' group to cause a buffer overflow and execute arbitrary code with root privileges.
5) The problem is that some of the WebSM Remote Client files are installed with world-writable permissions, which can be exploited to e.g. write to the installed files.
The vulnerabilities are reported in version 5.2 and 5.3.
