Updated Ethereal packages that fix various security vulnerabilities are now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The ethereal package is a program for monitoring network traffic.

A number of security flaws have been discovered in Ethereal. On a system where Ethereal is running, a remote attacker could send malicious packets to trigger these flaws and cause Ethereal to crash or potentially execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2005-1456, CVE-2005-1457, CVE-2005-1458, CVE-2005-1459, CVE-2005-1460, CVE-2005-1461, CVE-2005-1462, CVE-2005-1463, CVE-2005-1464, CVE-2005-1465, CVE-2005-1466, CVE-2005-1467, CVE-2005-1468, CVE-2005-1469, and CVE-2005-1470 to these issues.

Users of ethereal should upgrade to these updated packages, which contain version 0.10.11 which is not vulnerable to these issues.

The remote host is affected by the vulnerability described in GLSA-200505-03 (Ethereal: Numerous vulnerabilities)

    There are numerous vulnerabilities in versions of Ethereal prior     to 0.10.11, including:
    The ANSI A and DHCP dissectors are     vulnerable to format string vulnerabilities.
    The DISTCC,     FCELS, SIP, ISIS, CMIP, CMP, CMS, CRMF, ESS, OCSP, PKIX1Explitit, PKIX     Qualified, X.509, Q.931, MEGACO, NCP, ISUP, TCAP and Presentation     dissectors are vulnerable to buffer overflows.
    The KINK, WSP,     SMB Mailslot, H.245, MGCP, Q.931, RPC, GSM and SMB NETLOGON dissectors     are vulnerable to pointer handling errors.
    The LMP, KINK,     MGCP, RSVP, SRVLOC, EIGRP, MEGACO, DLSw, NCP and L2TP dissectors are     vulnerable to looping problems.
    The Telnet and DHCP dissectors     could abort.
    The TZSP, Bittorrent, SMB, MGCP and ISUP     dissectors could cause a segmentation fault.
    The WSP, 802.3     Slow protocols, BER, SMB Mailslot, SMB, NDPS, IAX2, RADIUS, SMB PIPE,     MRDISC and TCAP dissectors could throw assertions.
    The DICOM,     NDPS and ICEP dissectors are vulnerable to memory handling errors.
    The GSM MAP, AIM, Fibre Channel,SRVLOC, NDPS, LDAP and NTLMSSP     dissectors could terminate abnormallly.
  Impact :

    An attacker might be able to use these vulnerabilities to crash     Ethereal and execute arbitrary code with the permissions of the user     running Ethereal, which could be the root user.
  Workaround :

    There is no known workaround at this time.

A number of vulnerabilities were discovered in previous version of Ethereal that have been fixed in the 0.10.11 release, including :

  - The ANSI A and DHCP dissectors are vulnerable to format     string vulnerabilities.
