Two vulnerabilities have been found in unzip, a de-archiver for .zip

following problems:

CVE-2015-7696

    Gustavo Grieco discovered that unzip incorrectly handled certain
    password protected archives. If a user or automated system were
    tricked into processing a specially crafted zip archive, an attacker
    could possibly execute arbitrary code.

    Gustavo Grieco discovered that unzip incorrectly handled certain
    malformed archives. If a user or automated system were tricked into
    processing a specially crafted zip archive, an attacker could
    possibly cause unzip to hang, resulting in a denial of service.

For the oldstable distribution (wheezy), these problems have been fixed
in version 6.0-8+deb7u4.
