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.

For the stable distribution (wheezy), this problem has been fixed in version 6.0-8+deb7u2. Additionally this update corrects a defective patch applied to address CVE-2014-8139, which caused a regression with executable jar files.
