A vulnerability, which was classified as critical, has been found in Wireshark (Packet Analyzer Software). This issue affects an unknown function of the file epan/dissectors/packet-ber.c of the component ASN.1 BER Dissector. The manipulation as part of a Packet leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the ASN.1 BER and related dissectors could crash. This was addressed in epan/dissectors/packet-ber.c by preventing a buffer overflow associated with excessive digits in time values.

The bug was discovered 02/27/2019. The weakness was published 02/28/2019 by Mateusz Jurczyk (OSS-Fuzz) (Website). The advisory is shared at securityfocus.com. The identification of this vulnerability is CVE-2019-9209 since 02/26/2019. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation.
