More information:

A flaw was found in the test_compr_eb() function allowing out-of-bounds read and write access to memory locations. By carefully crafting a corrupt ZIP archive an attacker can trigger a heap overflow, resulting in application crash or possibly having other unspecified impact.

Additionally this update corrects a defective patch applied to address CVE-2014-8139, which caused a regression with executable jar files.

For Debian 6 Squeeze, these issues have been fixed in unzip version 6.0-4+deb6u2
