Updated Ethereal packages fix security issues

Updated Ethereal packages available to fix a number of remotely
exploitable security issues

Ethereal is a program for monitoring network traffic.

A number of security issues affect Ethereal. By exploiting these issues it
may be possible to make Ethereal crash or run arbitrary code by injecting a
purposefully malformed packet onto the wire or by convincing someone to
read a malformed packet trace file.

Multiple off-by-one vulnerabilities exist in Ethereal 0.9.11 and earlier in
the AIM, GIOP Gryphon, OSPF, PPTP, Quake, Quake2, Quake3, Rsync, SMB, SMPP,
and TSP dissectors. They do not properly use the tvb_get_nstringz and
tvb_get_nstringz0 functions. Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0356 to these issues.

Multiple integer overflow vulnerabilities exist in Ethereal 0.9.11 and
earlier in the Mount and PPP dissectors. (CAN-2003-0357)

A vulnerability in the DCERPC dissector exists in Ethereal 0.9.12 and
earlier, allowing remote attackers to cause a denial of service (memory
consumption) via a certain NDR string. (CAN-2003-0428)

The OSI dissector in Ethereal 0.9.12 and earlier causes by invalid IPv4 or
IPv6 prefix lengths, possibly triggering a buffer overflow. (CAN-2003-0429)

The SPNEGO dissector in Ethereal 0.9.12 and earlier allows remote attackers
to cause a denial of service (crash) via an invalid ASN.1 value.
(CAN-2003-0430)

The tvb_get_nstringz0 function in Ethereal 0.9.12 and earlier does not
properly handle a zero-length buffer size. (CAN-2003-0431)

Ethereal 0.9.12 and earlier does not handle certain strings properly in the
BGP, WTP, DNS, 802.11, ISAKMP, WSP, CLNP, ISIS, and RMI dissectors.
(CAN-2003-0432)

Users of Ethereal should update to the erratum packages containing Ethereal
version 0.9.13, which are not vulnerable to these issues.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

Please note that this update is available via Red Hat Network. To use Red
Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
