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.
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.
For the unstable distribution (sid), these problems have been fixed in
version 6.0-13.
We recommend that you upgrade your unzip packages.
