Debian Security Advisory

DLA-1239-1 poco -- LTS security update

Date Reported:
10 Jan 2018
Affected Packages:
poco
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2017-1000472.
More information:

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.

For Debian 7 Wheezy, these problems have been fixed in version 1.3.6p1-4+deb7u1.

We recommend that you upgrade your poco packages.
