Background ========== libextractor is a library used to extract metadata from arbitrary files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/libextractor < 0.5.14 >= 0.5.14 Description =========== Luigi Auriemma has found two heap-based buffer overflows in libextractor 0.5.13 and earlier: one of them occurs in the asf_read_header function in the ASF plugin, and the other occurs in the parse_trak_atom function in the Qt plugin. Impact ====== By enticing a user to open a malformed file using an application that employs libextractor and its ASF or Qt plugins, an attacker could execute arbitrary code in the context of the application running the affected library. Workaround ========== There is no known workaround at this time. Resolution ========== All libextractor users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libextractor-0.5.14" References ========== [ 1 ] CVE-2006-2458 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2458 [ 2 ] Original advisory http://aluigi.altervista.org/adv/libextho-adv.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200605-14.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.
