Mandrake Linux Security Update Advisory

---

Package name:	ethereal
Advisory ID:	MDKSA-2003:114
Date:	December 10th, 2003
Affected versions:	9.1, 9.2

---

Problem Description:

A number of vulnerabilities were discovered in ethereal that, if exploited, could be used to make ethereal crash or run arbitrary code by injecting malicious malformed packets onto the wire or by convincing someone to read a malformed packet trace file.

A buffer overflow allows attackers to cause a DoS (Denial of Service) and possibly execute arbitrary code using a malformed GTP MSISDN string (CAN-2003-0925).

Likewise, a DoS can be caused by using malformed ISAKMP or MEGACO packets (CAN-2003-0926).

Finally, a heap-based buffer overflow allows attackers to cause a DoS or execute arbitrary code using the SOCKS dissector (CAN-2003-0927).

All three vulnerabilities affect all versions of Ethereal up to and including 0.9.15. This update provides 0.9.16 which corrects all of these issues. Also note that each vulnerability can be exploited by a remote attacker.
