GLSA-200805-05 : Wireshark: Denial of Service
Medium Nessus Plugin ID 32153
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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).
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.
SolutionAll Wireshark users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-analyzer/wireshark-1.0.0'
