Wireshark: Denial of service

Wireshark: Denial of service Multiple Denial of Service vulnerabilities have been discovered in Wireshark. wireshark 2008-05-07 2008-05-07 215276 remote 1.0.0 1.0.0

Wireshark is a network protocol analyzer with a graphical front-end.

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).

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.

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

All Wireshark users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.0"
