Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2014-6429)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
2) Input validation error (CVE-ID: CVE-2014-6430)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
3) Buffer overflow (CVE-ID: CVE-2014-6431)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
4) Resource management error (CVE-ID: CVE-2014-6432)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
5) Buffer overflow (CVE-ID: CVE-2014-6428)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
6) Buffer overflow (CVE-ID: CVE-2014-6427)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
Off-by-one error in the is_rtsp_request_or_reply function in epan/dissectors/packet-rtsp.c in the RTSP 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 (application crash) via a crafted packet that triggers parsing of a token located one position beyond the current position.
7) Buffer overflow (CVE-ID: CVE-2014-6424)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The dissect_v9_v10_pdu_data function in epan/dissectors/packet-netflow.c in the Netflow dissector in Wireshark 1.10.x before 1.10.10 and 1.12.x before 1.12.1 refers to incorrect offset and start variables, which allows remote attackers to cause a denial of service (uninitialized memory read and application crash) via a crafted packet.
8) Resource management error (CVE-ID: CVE-2014-6423)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
9) Input validation error (CVE-ID: CVE-2014-6421)
The vulnerability allows remote attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (application crash) via a crafted packet that leverages split memory ownership between the SDP and RTP dissectors.
10) Buffer overflow (CVE-ID: CVE-2014-6422)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The SDP dissector in Wireshark 1.10.x before 1.10.10 creates duplicate hashtables for a media channel, which allows remote attackers to cause a denial of service (application crash) via a crafted packet to the RTP dissector.
