|Gentoo Linux Security Advisory
Title: Wireshark: Denial of Service (GLSA 200805-05)
Date: May 07, 2008
Multiple Denial of Service vulnerabilities have been discovered in Wireshark.
Wireshark is a network protocol analyzer with a graphical front-end.
Vulnerable: < 1.0.0
Unaffected: >= 1.0.0
Architectures: All supported architectures
Errors exist in:
- the X.509sat dissector because of an uninitialized variable and the Roofnet dissector because a NULL pointer may be passed to the g_vsnprintf() function (CVE-2008-1561).
- the LDAP dissector because a NULL pointer may be passed to the ep_strdup_printf() function (CVE-2008-1562).
- the SCCP dissector because it does not reset a pointer once the packet has been processed (CVE-2008-1563).
A remote attacker could exploit these vulnerabilities by sending a malformed packet or enticing a user to read a malformed packet trace file, causing a Denial of Service.
Disable the X.509sat, Roofnet, LDAP, and SCCP dissectors.
All Wireshark users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.0"
