Detailsinfo

A vulnerability was found in Wireshark up to 1.12.9/2.0.1 (Packet Analyzer Software). It has been classified as critical. This affects the function dissct_rsl_ipaccess_msg of the file epan/dissectors/packet-rsl.c of the component RSL Dissector. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The dissct_rsl_ipaccess_msg function in epan/dissectors/packet-rsl.c in the RSL dissector in Wireshark 1.12.x before 1.12.10 and 2.0.x before 2.0.2 mishandles the case of an unrecognized TLV type, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet, a different vulnerability than CVE-2016-2531.

The weakness was published 02/28/2016 by Mateusz Jurczyk (Website). The advisory is shared at code.wireshark.org. This vulnerability is uniquely identified as CVE-2016-2530 since 02/19/2016. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. 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 168802 (SUSE Enterprise Linux Security update for wireshark (SUSE-SU-2016:1344-1)).

Upgrading to version 1.12.10 or 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 (111122), Tenable (89048), SecurityFocus (BID 83388†) and Vulnerability Center (SBV-56944†).
