SUSE Security Announcement Package: realplayer 8 Announcement-ID: SUSE-SA:2005:004 Date: Monday, Jan 24th 2005 16:00 MET Affected products: 8.1, 8.2, 9.0, 9.1 SUSE Linux Desktop 1.0 Vulnerability Type: remote code execution Severity (1-10): 8 SUSE default package: yes Cross References: none Content of this advisory: 1) security vulnerability discussed: - integer overflow problem description 2) solution/workaround 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion RealPlayer is a combined audio and video player for RealMedia formatted streaming data. These formats are very common throughout the Internet. eEye Security in October 2004 discovered a flaw in the .rm RealMovie stream handling routines which allows a remote attacker to exploit an integer overflow vulnerability using a special .rm file. This might allow a remote attacker to execute code as the user running RealPlayer. Reference URLs for this problems are the Real security advisory: http://service.real.com/help/faq/security/040928_player/EN/ and the eEye security advisory: http://www.eeye.com/html/research/advisories/AD20041001.html SUSE Linux includes RealPlayer as both standalone player and as a plugin for web browsers like Mozilla and Konqueror. This might allow the attacker to just provide a web page or E-Mail linking to the special exploit .rm file. We cannot fully evaluate the impact of this problem due to lack of information and lack of source code to review. SUSE Linux versions up to 9.1 and the SUSE Linux Desktop 1.0 include RealPlayer version 8 and are affected by this problem. SUSE Linux 9.2 and the Novell Linux Desktop 9 include RealPlayer version 10 and are NOT affected by this problem. Real does not offer a fixed version 8 RealPlayer, but suggests upgrading RealPlayer to version 10. However, upgrading Realplayer is not possible for older SUSE Linux products since Realplayer 10 requires newer dynamic library versions than the ones to be found in those products. Also some old Real content is not compatible with the RealPlayer version 10. For these reasons we cannot offer fixed packages for older SUSE Linux based products. 2) solution/workaround We suggest one of the following workarounds: a) De-install RealPlayer Either use YaST to deinstall RealPlayer, or as root do: # rpm -e RealPlayer You will lose the ability to view Real content. b) Remove the RealPlayer plug in As root, execute the following commands: # rm /usr/lib/browser-plugins/raclass.zip # rm /usr/lib/browser-plugins/rpnp.so Content can still be viewed by starting "realplay" and opening URLs, but automatic exploits via web pages or E-Mails are no longer possible.
