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

The following vulnerabilities were reported:

Multiple buffer overflows in the NCP dissector (CVE-2008-3146).
Infinite loop in the NCP dissector (CVE-2008-3932).
Invalid read in the tvb_uncompress() function when processing zlib compressed data (CVE-2008-3933).
Unspecified error when processing Textronix .rf5 files (CVE-2008-3934).

A remote attacker could exploit these vulnerabilities by sending specially crafted packets on a network being monitored by Wireshark or by enticing a user to read a malformed packet trace file, causing a Denial of Service.

There is no known workaround at this time.

All Wireshark users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.3"
