Wireshark is a network protocol analyzer with a graphical front-end.
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"
