Base vector

AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: libming version 0.4.8

Description: The issue is related to a heap-based buffer over-read in the getName function of util/decompile.c, specifically for CONSTANT16 data. This can be triggered by a crafted input, potentially leading to a denial of service or other unspecified impacts.

Recommendations: For libming version 0.4.8, consider avoiding the use of the getName function in util/decompile.c for CONSTANT16 data until a fix is available. As a temporary workaround, restrict the input to prevent crafted data from being processed. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
