Summary
Red Hat Security Advisory: : Updated libxml2 packages fix security vulnerability

Notes

Topic
Updated libxml2 packages that fix an overflow when parsing remote resources are now available. [Updated 3 March 2004] Revised libxml2 packages are now available as the original packages did not contain a complete patch.
Details
libxml2 is a library for manipulating XML files. Yuuichi Teranishi discovered a flaw in libxml2 versions prior to 2.6.6. When fetching a remote resource via FTP or HTTP, libxml2 uses special parsing routines. These routines can overflow a buffer if passed a very long URL. If an attacker is able to find an application using libxml2 that parses remote resources and allows them to influence the URL, then this flaw could be used to execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0110 to this issue. All users are advised to upgrade to these updated packages, which contain a backported fix and are not vulnerable to this issue.

Only those\nRPMs which are currently installed will be updated.  Those RPMs which are\nnot installed but included in the list will not be updated.  Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network.  Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.\n\nIf up2date fails to connect to Red Hat Network due to SSL\nCertificate Errors, you need to install a version of the\nup2date client with an updated certificate.  The latest version of\nup2date is available from the Red Hat FTP site and may also be\ndownloaded directly from the RHN website:\n\nhttps://rhn.redhat.com/help/latest-up2date.pxt",
