Name of the Vulnerable Software and Affected Versions Open Chinese Convert (OpenCC) version 1.0.5

Description The issue allows attackers to cause a denial of service, resulting in a segmentation fault. This occurs because the BinaryDict::NewFromFile function in BinaryDict.cpp may have out-of-bounds keyOffset and valueOffset values when processing a crafted .ocd file.

Recommendations For Open Chinese Convert (OpenCC) version 1.0.5, as a temporary workaround, consider restricting the use of crafted .ocd files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
