Yellow Dog Linux Security Announcement -------------------------------------- Package: ethereal Issue Date: Apr 23,2003 Priority: medium Advisory ID: YDU-20030423-1 1. Topic: Updated ethereal packages are available. 2. Problem: "Ethereal is a package designed for monitoring network traffic on your system. Ethereal 0.9.9 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via carefully crafted SOCKS packets. Red Hat would like to thank Georgi Guninski for reporting this issue. Additionally, a heap-based buffer overflow in the NTLMSSP code for Ethereal 0.9.9 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code. Users of Ethereal should update to the erratum packages containing Ethereal version 0.9.11 which are not vulnerable to these issues." (From Red Hat Advisory) 3. Solution: a) Updating via apt... We suggest that you use the apt-get program to keep your system up-to-date. The following command(s) will retrieve and install the fixed version of this update onto your system: apt-get update apt-get install ethereal b) Updating manually... Download the updates below and then run the following rpm command.
