Background ========== The zziplib library is a lightweight library for extracting data from files archived in a single zip file. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/zziplib < 0.13.49 >= 0.13.49 Description =========== dmcox dmcox discovered a boundary error in the zzip_open_shared_io() function from zzip/file.c . Impact ====== A remote attacker could entice a user to run a zziplib function with an overly long string as an argument which would trigger the buffer overflow and may lead to the execution of arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All zziplib users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/zziplib-0.13.49" References ========== [ 1 ] CVE-2007-1614 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1614 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200704-05.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
