|Gentoo Linux Security Advisory
Title: Wireshark: Multiple Denials of Service (GLSA 200809-17)
Date: September 25, 2008
Multiple Denial of Service vulnerabilities have been discovered in Wireshark.
Wireshark is a network protocol analyzer with a graphical front-end.
Vulnerable: < 1.0.3
Unaffected: >= 1.0.3
Architectures: All supported architectures
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"
