-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SCO Security Advisory Subject: OpenLinux: wget: Buffer overflow Advisory number: CSSA-2003-025.0 Issue date: 2003 October 03 Cross reference: sr883607 fz528216 erg712410 CAN-2003-1565 ______________________________________________________________________________ 1. Problem Description wget is a freely available network utility to retrieve files using HTTP and FTP. Stefano Zacchirol found a buffer overflow vulnerability in the code that handles URLs in wget. An attacker can create a long (more than 256 characters), specially crafted URL that when parsed by wget can cause the execution of arbitrary code or program misbehavior. The packages included in this update fix the problem by unconditionally terminating long URLs in all cases. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-1565 to this issue. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to wget-1.8.2-1.i386.rpm OpenLinux 3.1.1 Workstation prior to wget-1.8.2-1.i386.rpm 3. Solution The proper solution is to install the latest packages. Many customers find it easier to use the Caldera System Updater, called cupdate (or kcupdate under the KDE environment), to update these packages rather than downloading and installing them by hand. 4. OpenLinux 3.1.1 Server 4.1 Package Location ftp://ftp.sco.com/pub/updates/OpenLinux/3.1.1/Server//RPMS 4.2 Packages c60a6e417ac41287973735f2c82d461c wget-1.8.2-1.i386.rpm 4.3 Installation rpm -Fvh wget-1.8.2-1.i386.rpm 4.4 Source Package Location ftp://ftp.sco.com/pub/updates/OpenLinux/3.1.1/Server//SRPMS 4.5 Source Packages 8ef3938fd5d49cc029b43c6b21cef9e0 wget-1.8.2-1.src.rpm 5.
