- Updated Ethereal packages that fix two security vulnerabilities are now
- available.
-
- Ethereal is a program for monitoring network traffic.
-
- Two security issues have been found that affect Ethereal. By exploiting
- these issues it may be possible to make Ethereal crash by injecting an
- intentionally malformed packet onto the wire or by convincing someone to
- read a malformed packet trace file. It is not known if these issues could
- allow arbitrary code execution.
-
- The SMB dissector in Ethereal before 0.10.0 allows remote attackers to
- cause a denial of service via a malformed SMB packet that triggers a
- segmentation fault during processing of Selected packets. The Common
- Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
- CAN-2003-1012 to this issue.
-
- The Q.931 dissector in Ethereal before 0.10.0 allows remote attackers to
- cause a denial of service (crash) via a malformed Q.931, which triggers a
- null dereference. The Common Vulnerabilities and Exposures project
- (cve.mitre.org) has assigned the name CAN-2003-1013 to this issue.
-
- Users of Ethereal should update to these erratum packages containing
- Ethereal version 0.10.0, which is not vulnerable to these issues.
