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 Debian 6 Squeeze, these issues have been fixed in unzip version 6.0-4+deb6u1
