‘unzip -l’ (CVE-2014-9913) and ‘zipinfo’ (CVE-2016-9844) were vulnerable to buffer overflows when provided malformed or maliciously-crafted ZIP files.
For Debian 7 ‘Wheezy’, these problems have been fixed in version 6.0-8+deb7u6.
We recommend that you upgrade your unzip packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
