Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2017-6469)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is an LDSS dissector crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-ldss.c by ensuring that memory is allocated for a certain data structure.
2) Infinite loop (CVE-ID: CVE-2017-6472)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is an RTMPT dissector infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-rtmpt.c by properly incrementing a certain sequence value.
3) Input validation error (CVE-ID: CVE-2017-6471)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a WSP infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-wsp.c by validating the capability length.
4) Infinite loop (CVE-ID: CVE-2017-6474)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a NetScaler file parser infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by validating record sizes.
5) Input validation error (CVE-ID: CVE-2017-6468)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a NetScaler file parser crash, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by validating the relationship between pages and records.
6) Input validation error (CVE-ID: CVE-2017-6473)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a K12 file parser crash, triggered by a malformed capture file. This was addressed in wiretap/k12.c by validating the relationships between lengths and offsets.
7) Infinite loop (CVE-ID: CVE-2017-6470)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is an IAX2 infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-iax2.c by constraining packet lateness.
8) Infinite loop (CVE-ID: CVE-2017-6467)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a Netscaler file parser infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by changing the restrictions on file size.
