| 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.
