libsmi smiGetNode() buffer overflow

libsmi-smigetnode-bo (62686) The risk level is classified as HighHigh Risk

Description:

libsmi is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the smiGetNode() function when processing an Object Identifier (OID) in string-dotted notation. By sending an overly long string, a local attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
