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. For the unstable distribution (sid), this problem has been fixed in version 6.0-15. The defective patch applied to address CVE-2014-8139 was corrected in version 6.0-16. We recommend that you upgrade your unzip packages.

InfoZIP's unzip program. With the exception of multi-volume archives (ie, .ZIP files that are split across several disks using PKZIP's /& option), this can handle any file produced either by PKZIP, or the corresponding InfoZIP zip program.
