Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2019-10894)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the GSS-API dissector could crash. This was addressed in epan/dissectors/packet-gssapi.c by ensuring that a valid dissector is called.
2) Input validation error (CVE-ID: CVE-2019-10895)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the NetScaler file parser could crash. This was addressed in wiretap/netscaler.c by improving data validation.
3) Resource management error (CVE-ID: CVE-2019-10896)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the DOF dissector could crash. This was addressed in epan/dissectors/packet-dof.c by properly handling generated IID and OID bytes.
4) Buffer overflow (CVE-ID: CVE-2019-10899)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the SRVLOC dissector could crash. This was addressed in epan/dissectors/packet-srvloc.c by preventing a heap-based buffer under-read.
5) NULL pointer dereference (CVE-ID: CVE-2019-10901)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the LDSS dissector could crash. This was addressed in epan/dissectors/packet-ldss.c by handling file digests properly.
6) Resource management error (CVE-ID: CVE-2019-10903)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the DCERPC SPOOLSS dissector could crash. This was addressed in epan/dissectors/packet-dcerpc-spoolss.c by adding a boundary check.
