Background ========== libarchive is a library for manipulating different streaming archive formats, including certain tar variants, several cpio formats, and both BSD and GNU ar variants. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/libarchive < 2.2.4 >= 2.2.4 Description =========== CPNI, CERT-FI, Tim Kientzle, and Colin Percival reported a buffer overflow (CVE-2007-3641), an infinite loop (CVE-2007-3644), and a NULL pointer dereference (CVE-2007-3645) within the processing of archives having corrupted PaX extension headers. Impact ====== An attacker can trick a user or automated system to process an archive with malformed PaX extension headers into execute arbitrary code, crash an application using the library, or cause a high CPU load. Workaround ========== There is no known workaround at this time. Resolution ========== All libarchive or bsdtar users should upgrade to the latest libarchive version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/libarchive-2.2.4" References ========== [ 1 ] CVE-2007-3641 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3641 [ 2 ] CVE-2007-3644 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3644 [ 3 ] CVE-2007-3645 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3645 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200708-03.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.
