This is related to: SA11510 SA12435 2) A boundary error exists during the construction of an error message when attempting to extract an invalid LZH file. This can be exploited to cause a stack-based buffer overflow when a specially crafted LZH file with an invalid CRC checksum is extracted. Successful exploitation of the vulnerabilities allows execution of arbitrary code. The vulnerabilities have been reported in version 1.31 (Japanese). Prior versions may also be affected. SOLUTION: Update to version 1.32.
