Debian DLA-330-1 : unzip security update

medium Nessus Plugin ID 86551


The remote Debian host is missing a security update.


Gustavo Grieco discovered with a fuzzer that unzip was vulnerable to a heap overflow and to a denial of service with specially crafted password-protected ZIP archives.

For the Debian 6 squeeze, these issues haven been fixed in unzip 6.0-4+deb6u3.

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.


Upgrade the affected unzip package.
