A few vulnerabilities were found in Wireshark, that could cause it to crash or hang under certain conditions.

This update provides Wireshark 1.0.0, which is not vulnerable to the issues.

Multiple buffer overflow flaws were found in Wireshark. If Wireshark read a malformed packet off a network, it could crash or, possibly, execute arbitrary code as the user running Wireshark. (CVE-2008-3146)

Several denial of service flaws were found in Wireshark. Wireshark could crash or stop responding if it read a malformed packet off a network, or opened a malformed dump file. (CVE-2008-1070, CVE-2008-1071, CVE-2008-1072, CVE-2008-1561, CVE-2008-1562, CVE-2008-1563, CVE-2008-3137, CVE-2008-3138, CVE-2008-3141, CVE-2008-3145, CVE-2008-3932, CVE-2008-3933, CVE-2008-3934)

Additionally, this update changes the default Pluggable Authentication Modules (PAM) configuration to always prompt for the root password before each start of Wireshark. This avoids unintentionally running Wireshark with root privileges.

Upgrade to 1.0.0 fixes several security flaws (wireshark crashes, see BZ references).

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated wireshark packages that fix several security issues are now available for Red Hat Enterprise Linux 3, 4, and 5.

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

Users of wireshark should upgrade to these updated packages, which contain Wireshark version 1.0.3, and resolve these issues.

Multiple flaws in wireshark could lead to crashes when certain packets are processed (CVE-2008-1561,CVE-2008-1562,CVE-2008-1563)

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2008-0890 advisory.

    [1.0.3-4.0.1.el5_2]
    - Add oracle-ocfs2-network.patch

    [1.0.3-4]
    - fix pam session file, wireshark requires root pswd everytime its started

    [1.0.3-3]
    - fix pie flags

    [1.0.3-1]
    - upgrade to 1.0.3
    - fixes several security issues
    - Resolves: #461569

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-200805-05 (Wireshark: Denial of Service)

    Errors exist in:
    the X.509sat dissector because of an uninitialized variable and the     Roofnet dissector because a NULL pointer may be passed to the     g_vsnprintf() function (CVE-2008-1561).
    the LDAP dissector because a NULL pointer may be passed to the     ep_strdup_printf() function (CVE-2008-1562).
    the SCCP dissector because it does not reset a pointer once the packet     has been processed (CVE-2008-1563).
  Impact :

    A remote attacker could exploit these vulnerabilities by sending a     malformed packet or enticing a user to read a malformed packet trace     file, causing a Denial of Service.
  Workaround :

    Disable the X.509sat, Roofnet, LDAP, and SCCP dissectors.
