Synopsis

Multiple Denial of Service vulnerabilities have been discovered in Wireshark.

2. Impact Information

Background

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

Description

Multiple vulnerabilities related to memory management were discovered in the GSM SMS dissector (CVE-2008-3137), the PANA and KISMET dissectors (CVE-2008-3138), the RTMPT dissector (CVE-2008-3139), the syslog dissector (CVE-2008-3140) and the RMI dissector (CVE-2008-3141) and when reassembling fragmented packets (CVE-2008-3145).

Impact

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

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Wireshark users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.2"
