Title: Unicon-imc2 Environment Variable Buffer Overflow Vulnerability
Severity: MODERATE
Description:
The 'unicon-imc2' package is a Chinese input-method library and API.
The software is affected by a local buffer-overflow vulnerability because it fails to perform boundary checks before copying user-supplied data into sensitive process buffers.
This issue presents itself when the affected application handles a long value supplied through an environment variable. An attacker can supply an excessive string value through the variable to overflow a finite-sized destination buffer. This can lead to memory corruption and allow the attacker to execute arbitrary code on the affected computer.
A successful attack may allow the attacker to gain elevated privileges in the context of the application.
This issue affects unicon-imc2 3.0.4; oher versions may be affected as well.
