Mandrake Linux Security Update Advisory

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.
