CSN.1 protocol dissector crash in 4.6.0 to 4.6.8 and 4.4.0 to 4.4.18 allows denial of service
A flaw was found in Wireshark's CSN.1 (Concrete Syntax Notation One) protocol dissector. By transmitting malformed network packets or providing a crafted packet capture file, an attacker can trigger a heap-based buffer overflow. This vulnerability causes the application to crash, leading to a Denial of Service (DoS).
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
