CVE-2005-0699
Multiple buffer overflows in the dissect_a11_radius function in the
CDMA A11 (3G-A11) dissector (packet-3g-a11.c) for Ethereal 0.10.9 and
earlier allow remote attackers to execute arbitrary code via RADIUS
authentication packets with large length values.

CVE-2005-0704
Buffer overflow in the Etheric dissector in Ethereal 0.10.7 through
0.10.9 allows remote attackers to cause a denial of service
(application crash) and possibly execute arbitrary code.

CVE-2005-0705
The GPRS-LLC dissector in Ethereal 0.10.7 through 0.10.9, with the
'ignore cipher bit' option enabled. allows remote attackers to cause a
denial of service (application crash).

CVE-2005-0739
The IAPP dissector (packet-iapp.c) for Ethereal 0.9.1 to 0.10.9 does
not properly use certain routines for formatting strings, which could
leave it vulnerable to buffer overflows, as demonstrated using
modified length values that are not properly handled by the
dissect_pdus and pduval_to_str functions.");
