Debian Security Advisory DSA-3152-1 security@debian.org
http://www.debian.org/security/ Salvatore Bonaccorso
February 03, 2015 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : unzip
CVE ID : CVE-2014-9636
Debian Bug : 776589
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.
