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 531742 (Enterprise Manager) to this vulnerability, and has evaluated the currently supported releases for potential vulnerability.

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.
