Detailsinfo

A vulnerability was found in Wireshark 2.0.0/2.0.1 (Packet Analyzer Software). It has been declared as problematic. Affected by this vulnerability is the function dissect_ber_constrained_bitstring of the file epan/dissectors/packet-ber.c of the component ASN.1 BER Dissector. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect availability. The summary by CVE is:

The dissect_ber_constrained_bitstring function in epan/dissectors/packet-ber.c in the ASN.1 BER dissector in Wireshark 2.0.x before 2.0.2 does not verify that a certain length is nonzero, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet.

The weakness was disclosed 02/28/2016 by Mateusz Jurczyk with Wireshark (Website). The advisory is shared at code.wireshark.org. This vulnerability is known as CVE-2016-2522 since 02/20/2016. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 89048 (FreeBSD : wireshark -- multiple vulnerabilities (45117749-df55-11e5-b2bd-002590263bf5)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 124753 (Wireshark Multiple Denial of Service Vulnerabilities (wnpa-sec-2016-01 to wnpa-sec-2016-18)).

Upgrading to version 2.0.2 eliminates this vulnerability. A possible mitigation has been published 2 days after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (111109), Tenable (89048), SecurityFocus (BID 83580†) and Vulnerability Center (SBV-56936†). The entries VDB-81096, VDB-81098, VDB-81099 and VDB-81100 are pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
