Security vulnerability with IBM Advanced Settings Utility (ASU) and IBM
Bootable Media Creator (BoMC) when used under the Linux operating system
(CVE-2012-3329) - IBM Flex System, System x and BladeCenter
Summary
* When (1) ASU or BoMC are used in the Linux operating system, and (2) log
files and/or temporary files created by ASU or BoMC are linked to system
and/or user files, then the system and/or user files could be overwritten.
Overwriting these system and/or user files could result in corruption of the
operating system.
Vulnerability Details
CVE ID: CVE-2012-3329
Description:
ASU and BoMC use hardcoded temporary and/or log file names, which are
predictable. Any user or malicious entity even without root access could use
these predictable file names to create links between the temporary and/or log
files and system and/or user files. When ASU and BoMC are used in the Linux
operating system, the linking of these files causes the system and/or user
files to be overwritten. If the system and/or user files are overwritten, the
operating system could become corrupted. A fix has been developed to address
this issue. See below for information about locating and installing the fix.
The following ASU code levels exhibit this behavior:
ASU level 3.62 or earlier and 3.70 through 9.21
The following BoMC code levels exhibit this behavior:
BoMC level 2.30 or earlier and 3.00 through 9.21
