Debian DSA-3113-1 : unzip - security update

high Nessus Plugin ID 80255

Synopsis

The remote Debian host is missing a security-related update.

Description

Michele Spagnuolo of the Google Security Team discovered that unzip, an extraction utility for archives compressed in .zip format, is affected by heap-based buffer overflows within the CRC32 verification function (CVE-2014-8139 ), the test_compr_eb() function (CVE-2014-8140 ) and the getZip64Data() function (CVE-2014-8141 ), which may lead to the execution of arbitrary code.

Solution

Upgrade the unzip packages.

For the stable distribution (wheezy), these problems have been fixed in version 6.0-8+deb7u1.

For the upcoming stable distribution (jessie), these problems will be fixed soon.
