Background ========== Wireshark is a network protocol analyzer with a graphical front-end. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/wireshark < 0.99.6 >= 0.99.6 Description =========== Wireshark doesn't properly handle chunked encoding in HTTP responses (CVE-2007-3389), iSeries capture files (CVE-2007-3390), certain types of DCP ETSI packets (CVE-2007-3391), and SSL or MMS packets (CVE-2007-3392). An off-by-one error has been discovered in the DHCP/BOOTP dissector when handling DHCP-over-DOCSIS packets (CVE-2007-3393). Impact ====== A remote attacker could send specially crafted packets on a network being monitored with Wireshark, possibly resulting in the execution of arbitrary code with the privileges of the user running Wireshark which might be the root user, or a Denial of Service. Workaround ========== In order to prevent root compromise, take network captures with tcpdump and analyze them running Wireshark as a least privileged user. Resolution ========== All Wireshark users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-0.99.6" References ========== [ 1 ] CVE-2007-3389 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3389 [ 2 ] CVE-2007-3390 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3390 [ 3 ] CVE-2007-3391 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3391 [ 4 ] CVE-2007-3392 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3392 [ 5 ] CVE-2007-3393 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3393 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200708-12.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
