Background ========== libxml2 is the XML (eXtended Markup Language) C parser and toolkit initially developed for the Gnome project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libxml2 < 2.6.30-r1 >= 2.6.30-r1 Description =========== Brad Fitzpatrick reported that the xmlCurrentChar() function does not properly handle some UTF-8 multibyte encodings. Impact ====== A remote attacker could entice a user to open a specially crafted XML document with an application using libxml2, possibly resulting in a high CPU consumption. Note that this vulnerability could also be triggered without user interaction by an automated system processing XML içerik. Workaround ========== There is no known workaround at this time.
