OpenPKG 1.3 <= libxml-2.5.8-1.3.0 >= libxml-2.5.8-1.3.1 Affected Releases: Dependent Packages: OpenPKG CURRENT apache::with_mod_php_dom perl-xml::with_libxml php::with_dom php5::with_xml php5::with_dom cadaver dia kde-libs libgdome libglade libwmf libxslt neon pan ripe-dbase roadrunner scli scrollkeeper sitecopy subversion wv xmlsec xmlstarlet xmlto xmms OpenPKG 1.3 apache::with_mod_php_dom perl-xml::with_libxml php::with_dom libgdome libwmf libxslt neon sitecopy xmlsec Description: A flaw in the HTTP and FTP client sub-library of libxml2 [0] found by Yuuichi Teranishi can be exploited to cause a buffer overflow if passed a very long URL [1]. This could be used by an attacker to execute arbitrary code on the host computer. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2004-0110 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/rpm -q libxml". If you have the "libxml" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see solution) and any dependent packages (see above). [3][4] Solution: Select the updated source RPM appropriate for your OpenPKG release [5], fetch it from the OpenPKG FTP service [6] or a mirror location, verify its integrity [7], build a corresponding binary RPM from it [3] and update your OpenPKG installation by applying the binary RPM [4]. For the affected release OpenPKG 1.3, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.3/UPD ftp> get libxml-2.5.8-1.3.1.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig libxml-2.5.8-1.3.1.src.rpm $ <prefix>/bin/rpm --rebuild libxml-2.5.8-1.3.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/libxml-2.5.8-1.3.1.*.rpm Additionally, we recommend that you rebuild and reinstall all dependent packages (see above), if any, too.
