This could lead to the execution of arbitrary code. Background ========== zip is a compression and file packaging utility. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/zip <= 2.3-r3 >= 2.3-r4 Description =========== zip does not check the resulting path length when doing recursive folder compression. Impact ====== An attacker could exploit this by enticing another user or web application to create an archive including a specially-crafted path name, potentially resulting in the execution of arbitrary code with the permissions of the user running zip. Workaround ========== There is no known workaround at this time. Resolution ========== All zip users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/zip-2.3-r4" References ========== [ 1 ] HexView zip Advisory http://www.hexview.com/docs/20041103-1.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200411-16.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.
