SOL16940: Multiple Wireshark vulnerabilities

Security Advisory

Original Publication Date: 07/08/2015

Description

CVE-2014-6423

The tvb_raw_text_add function in epan/dissectors/packet-megaco.c in the MEGACO
dissector in Wireshark 1.10.x before 1.10.10 and 1.12.x before 1.12.1 allows 
remote attackers to cause a denial of service (infinite loop) via an empty 
line.

CVE-2014-6425

The (1) get_quoted_string and (2) get_unquoted_string functions in 
epan/dissectors/packet-cups.c in the CUPS dissector in Wireshark 1.12.x before
1.12.1 allow remote attackers to cause a denial of service (buffer over-read 
and application crash) via a CUPS packet that lacks a trailing '\0' character.

CVE-2014-6428

The dissect_spdu function in epan/dissectors/packet-ses.c in the SES dissector
in Wireshark 1.10.x before 1.10.10 and 1.12.x before 1.12.1 does not 
initialize a certain ID value, which allows remote attackers to cause a denial
of service (application crash) via a crafted packet.

CVE-2014-6429

The SnifferDecompress function in wiretap/ngsniffer.c in the DOS Sniffer file
parser in Wireshark 1.10.x before 1.10.10 and 1.12.x before 1.12.1 does not 
properly handle empty input data, which allows remote attackers to cause a 
denial of service (application crash) via a crafted file.

CVE-2014-6430

The SnifferDecompress function in wiretap/ngsniffer.c in the DOS Sniffer file
parser in Wireshark 1.10.x before 1.10.10 and 1.12.x before 1.12.1 does not 
validate bitmask data, which allows remote attackers to cause a denial of 
service (application crash) via a crafted file.

CVE-2014-6431

Buffer overflow in the SnifferDecompress function in wiretap/ngsniffer.c in 
the DOS Sniffer file parser in Wireshark 1.10.x before 1.10.10 and 1.12.x 
before 1.12.1 allows remote attackers to cause a denial of service 
(application crash) via a crafted file that triggers writes of uncompressed 
bytes beyond the end of the output buffer.

CVE-2014-6432

The SnifferDecompress function in wiretap/ngsniffer.c in the DOS Sniffer file
parser in Wireshark 1.10.x before 1.10.10 and 1.12.x before 1.12.1 does not 
prevent data overwrites during copy operations, which allows remote attackers
to cause a denial of service (application crash) via a crafted file.

Impact

A remote attacker may be able to cause a denial-of-service (DoS).

Status

F5 Product Development has assigned ID 486791 (BIG-IP), 486791 (BIG-IQ) and

Note: As of February 17, 2015, AskF5 Security Advisory articles include the 
Severity value. Security Advisory articles published before this date do not 
list a Severity value.

Recommended Action

If the previous table lists a version in the Versions known to be not 
vulnerable column, you can eliminate this vulnerability by upgrading to the 
listed version. If the listed version is older than the version you are 
currently running, or if the table does not list any version in the column, 
then no upgrade candidate currently exists.

F5 responds to vulnerabilities in accordance with the Severity values 
published in the previous table. The Severity values and other security 
vulnerability parameters are defined in SOL4602: Overview of the F5 security 
vulnerability response policy.

To mitigate this vulnerability, you can use the tcpdump utility to perform 
packet captures instead of the tshark utility. For information about the 
tcpdump utility, refer to SOL411: Overview of packet tracing with the tcpdump
utility.
