Name of the Vulnerable Software and Affected Versions mruby version 1.4.1

Description The issue is related to the init copy function in kernel.c, which makes initialize copy calls for TT ICLASS objects. This allows attackers to cause a denial of service, resulting in an uninitialized pointer and application crash, or possibly have other unspecified impacts.

Recommendations For mruby version 1.4.1, consider disabling the init copy function in kernel.c as a temporary workaround until a patch is available. Restrict access to TT ICLASS objects to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
