GLSA-200805-05 : Wireshark: Denial of Service

medium Nessus Plugin ID 32153

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200805-05 (Wireshark: Denial of Service)

 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.

Solution

All Wireshark users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-analyzer/wireshark-1.0.0'
