Gentoo: GLSA-200801-20: libxml2: Denial of Service
Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200801-20 https://security.gentoo.org/
Severity: Normal Title: libxml2: Denial of Service Date: January 30, 2008 Bugs: #202628 ID: 200801-20
Synopsis ======= A Denial of Service vulnerability has been reported in libxml2.
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
========== 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 content.
Workaround ========= There is no known workaround at this time.
Resolution ========= All libxml2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.6.30-r1"
