--------------------------------------------------------------------- Fedora Legacy Update Advisory Synopsis: Updated lynx package fixes security issues Advisory ID: FLSA:152832 Issue date: 2005-12-17 Product: Red Hat Linux, Fedora Core Keywords: Bugfix CVE Names: CVE-2005-2929 CVE-2005-3120 --------------------------------------------------------------------- --------------------------------------------------------------------- 1. Topic: An updated lynx package that corrects security issues is now available. Lynx is a text-based Web browser. 2. Relevant releases/architectures: Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386 Fedora Core 2 - i386 3. Problem description: An arbitrary command execute bug was found in the lynx "lynxcgi:" URI handler. An attacker could create a web page redirecting to a malicious URL which could execute arbitrary code as the user running lynx. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-2929 to this issue. Ulf Harnhammar discovered a stack overflow bug in Lynx when handling connections to NNTP (news) servers. An attacker could create a web page redirecting to a malicious news server which could execute arbitrary code as the user running lynx. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-3120 to this issue. Users should update to this erratum package, which contains backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue: yum update or to use apt: apt-get update; apt-get upgrade This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get. 5.
