Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2017-11410)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

In Wireshark through 2.0.13 and 2.2.x through 2.2.7, the WBXML dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-wbxml.c by adding validation of the relationships between indexes and lengths. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-7702.


2) Input validation error (CVE-ID: CVE-2017-11411)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

In Wireshark through 2.0.13 and 2.2.x through 2.2.7, the openSAFETY dissector could crash or exhaust system memory. This was addressed in epan/dissectors/packet-opensafety.c by adding length validation. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-9350.
