## Description

The ZipCommon::isValidPath() function in Zip/src/ZipCommon.cpp in POCO C++
Libraries before 1.8 does not properly restrict the filename value in the
ZIP header, which allows attackers to conduct absolute path traversal
attacks during the ZIP decompression, and possibly create or overwrite
arbitrary files, via a crafted ZIP file, related to a "file path injection
vulnerability".
