Severity: Normal Title: Wireshark: Denial of Service Date: May 07, 2008 Bugs: #215276 ID: 200805-05

Synopsis ========
Multiple Denial of Service vulnerabilities have been discovered in Wireshark.
Background ==========
Wireshark is a network protocol analyzer with a graphical front-end.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/wireshark < 1.0.0 >= 1.0.0
Description ===========
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).
Impact ======
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.
Workaround ==========
Disable the X.509sat, Roofnet, LDAP, and SCCP dissectors.
Resolution ==========
All Wireshark users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.0"
