Description

Updated Ethereal packages that fix a number of exploitable security issues are now available.

Ethereal is a program for monitoring network traffic.

A number of security issues affect Ethereal. By exploiting these issues, it may be possible to make Ethereal crash or run arbitrary code by injecting a purposefully-malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

A buffer overflow in Ethereal 0.9.15 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via a malformed GTP MSISDN string. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0925 to this issue.

Ethereal 0.9.15 and earlier allows remote attackers to cause a denial of service (crash) via certain malformed ISAKMP or MEGACO packets. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0926 to this issue.

A heap-based buffer overflow in Ethereal 0.9.15 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the SOCKS dissector. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0927 to this issue.

Users of Ethereal should update to these erratum packages containing Ethereal version 0.9.16, which is not vulnerable to these issues.
