Description: A vulnerability has been reported in IBM AIX, which can be exploited by malicious, local users to gain escalated privileges. The vulnerability is caused due to a boundary error within odm_searchpath() in the libodm library when processing the ODMPATH environment variable. This can be exploited to cause a stack-based buffer overflow via an overly long ODMPATH variable. Successful exploitation allows execution of arbitrary code with root privileges. The vulnerability is reported in versions 5.2.0 and 5.3.0. Solution: Apply APARs: AIX 5.2.0: APAR IZ00531 AIX 5.3.0: APAR IZ01437 Provided and/or discovered by: Discovered by an anonymous person and reported via iDefense Labs.
