Updated Ethereal packages are available which fix various security issues.
Ethereal is a package designed for monitoring network traffic on your system. Several security issues have been found in the Ethereal packages distributed with Red Hat Linux versions 7.2, 7.3, and 8.0 Multiple integer signedness errors in the BGP dissector in Ethereal 0.9.7 and earlier allow remote attackers to cause a denial of service (infinite loop) via malformed messages. This problem was discovered by Silvio Cesare. CAN-2002-1355 Ethereal 0.9.7 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via malformed packets to the LMP, PPP, or TDS dissectors. CAN-2002-1356 Users of Ethereal should update to the erratum packages containing Ethereal version 0.9.8 which is not vulnerable to these issues.
