Ethereal 0.9.4
was released
on May 19, 2002 fixing four potential security issues in Ethereal 0.9.3:
The SMB dissector could potentially dereference a NULL pointer in two cases.
The X11 dissector could potentially overflow a buffer while parsing keysyms.
The DNS dissector could go into an infinite loop while reading a malformed packet.
The GIOP dissector could potentially allocate large amounts of memory.
No known exploits exist "in the wild" at the present time for any of these issues.
Ethereal 0.9.2 has several packet handling vulnerabilities
that are best avoided by upgrading to 0.9.4.
The PROTOS test
suite found some flaws in SNMP and LDAP protocols support.
Malformed packets could also crash ethereal 0.9.2 due to a
ASN.1 zero-length g_malloc problem.
The zlib "double free" vulnerability
was addressed by the updates for that bug from many distributors.
