CVE-2017-1000472: Debian Linux

Medium severity, CVSS 6.5. EPSS: 1.7% chance of exploitation in the next 30 days.

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".

Affected products

• Debian Debian Linux: version 8.0 only; version 9.0 only
• Pocoproject Poco: before 1.8 (fixed in 1.8)
