Wireshark: Denial of service

Background

Wireshark is a versatile network protocol analyzer.

Description

Multiple vulnerabilities were discovered in Wireshark:

• A buffer overflow in the IPMI dissector related to an array index error (CVE-2009-2559).
• Multiple unspecified vulnerabilities in the Bluetooth L2CAP, RADIUS, and MIOP dissectors (CVE-2009-2560).
• An unspecified vulnerability in the sFlow dissector (CVE-2009-2561).
• An unspecified vulnerability in the AFS dissector (CVE-2009-2562).
• An unspecified vulnerability in the Infiniband dissector when running on unspecified platforms (CVE-2009-2563).

Impact

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 to cause a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All Wireshark users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.2.1"
