-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SCO Security Advisory Subject: OpenLinux: mpg123 remote denial of service and heap-based buffer overflow Advisory number: CSSA-2004-002.0 Issue date: 2004 February 19 Cross reference: sr882700 fz528149 erg712383 CAN-2003-0577 CAN-2003-0865 ______________________________________________________________________________ 1. Problem Description mpg123 0.59r allows remote attackers to cause a denial of service and possibly execute arbitrary code via an MP3 file with a zero bitrate, which creates a negative frame size. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0577 to this issue. Heap-based buffer overflow in readstring of httpget.c for mpg123 0.59r and 0.59s allows remote attackers to execute arbitrary code via a long request. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0865 to this issue. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to mpg123-0.59r-7MR.i386.rpm OpenLinux 3.1.1 Workstation prior to mpg123-0.59r-7MR.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/CSSA-2004-00 2.0/RPMS 4.2 Packages cb8a81f231da3c943dfaa366df68045a mpg123-0.59r-7MR.i386.rpm 4.3 Installation rpm -Fvh mpg123-0.59r-7MR.i386.rpm 4.4 Source Package Location ftp://ftp.sco.com/pub/updates/OpenLinux/3.1.1/Server/CSSA-2004-00 2.0/SRPMS 4.5 Source Packages 810ef880b6ad68ea7aea631241552dad mpg123-0.59r-7MR.src.rpm 5.
