Andres Lopez Luksenberg has reported a vulnerability in libsmi, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a boundary error in the "smiGetNode()" function within lib/smi.c when processing an Object Identifier (OID) in string-dotted notation and can be exploited to cause a stack-based buffer overflow via an overly long specially crafted string.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is reported in version 0.4.8. Other versions may also be affected.
Solution: Fixed in the SVN repository.
Provided and/or discovered by: Andres Lopez Luksenberg, Core Security Technologies.
