4ae135f7-85cd-4c32-ad94-358271b31f7f | zeek -- potential denial of service issues
Jon Siwek of Corelight reports:
This release addresses the following security issues:
-
Potential Denial of Service due to memory leak in DNS
TSIG message parsing.
-
Potential Denial of Service due to memory leak (or assertion
when compiling with assertions enabled) when receiving a
second SSH KEX message after a first.
-
Potential Denial of Service due to buffer read overflow
and/or memory leaks in Kerberos analyzer. The buffer
read overflow could occur when the Kerberos message
indicates it contains an IPv6 address, but does not send
enough data to parse out a full IPv6 address. A memory
leak could occur when processing KRB_KDC_REQ KRB_KDC_REP
messages for message types that do not match a known/expected
type.
-
Potential Denial of Service when sending many zero-length
SSL/TLS certificate data. Such messages underwent the
full Zeek file analysis treatment which is expensive (and
meaninguless here) compared to how cheaply one can "create"
or otherwise indicate many zero-length contained in an
SSL message.
-
Potential Denial of Service due to buffer read overflow
in SMB transaction data string handling. The length of
strings being parsed from SMB messages was trusted to be
whatever the message claimed instead of the actual length
of data found in the message.
-
Potential Denial of Service due to null pointer dereference
in FTP ADAT Base64 decoding.
-
Potential Denial of Service due buffer read overflow in
FTP analyzer word/whitespace handling. This typically
won't be a problem in most default deployments of Zeek
since the FTP analyzer receives data from a ContentLine
(NVT) support analyzer which first null-terminates the
buffer used for further FTP parsing.

204f1a7a-43df-412f-ad25-7dbe88f54fa4 | zeek -- potential DoS vulnerabilty
Tim Wojtulewicz of Corelight reports:
Fix potential hang in the DNS analyzer when receiving
a specially-crafted packet. Due to the possibility of
this happening with packets received from the network,
this is a potential DoS vulnerability.

3110b29e-c82d-4287-9f6c-db82bb883b1e | zeek -- potential DoS vulnerabilities
Tim Wojtulewicz of Corelight reports:
Fix a possible overflow and crash in the ARP analyzer
when receiving a specially crafted packet. Due to the
possibility of this happening with packets received from
the network, this is a potential DoS vulnerability.
Fix a possible overflow and crash in the Modbus analyzer
when receiving a specially crafted packet. Due to the
possibility of this happening with packets received from
the network, this is a potential DoS vulnerability.
Fix two possible crashes when converting IP headers for
output via the raw_packet event. Due to the possibility of
this happening with packets received from the network, this
is a potential DoS vulnerability. Note that the raw_packet
event is not enabled by default so these are likely
low-severity issues.
Fix an abort related to an error related to the ordering
of record fields when processing DNS EDNS headers via events.
Due to the possibility of this happening with packets
received from the network, this is a potential DoS
vulnerability. Note that the dns_EDNS events are not
implemented by default so this is likely a low-severity
issue.

d4d21998-bdc4-4a09-9849-2898d9b41459 | zeek -- several vulnerabilities
Tim Wojtulewicz of Corelight reports:
Paths from log stream make it into system() unchecked,
potentially leading to commands being run on the system
unintentionally. This requires either bad scripting or a
malicious package to be installed, and is considered low
severity.
Fix potential unbounded state growth in the PIA
analyzer when receiving a connection with either a large
number of zero-length packets, or one which continues
ack-ing unseen segments. It is possible to run Zeek out
of memory in these instances and cause it to crash. Due
to the possibility of this happening with packets received
from the network, this is a potential DoS vulnerability.

This release fixes the following security issue:
- A memory leak in multipart MIME code has potential
for remote exploitation and cause for Denial of Service
via resource exhaustion.

Jon Siwek of Corelight reports:
Fix ASCII Input reader's treatment of input files
containing null-bytes. An input file containing null-bytes
could lead to a buffer-over-read, crash Zeek, and be
exploited to cause Denial of Service.

and decode_netbios_name_type() BIFs. The latter has a
possibility of a remote heap-buffer-overread, making this

ipv6 packets. Due to the possibility of reading invalid
headers from remote sources, this is a potential DoS
vulnerability.
