CVE-2023-4511
Description
A denial of service vulnerability was found in Wireshark due to an infinite loop in the Bluetooth (BT) SDP dissector. Exploiting this flaw involves injecting a malformed packet onto the wire or enticing a victim to read a corrupted packet trace file, resulting in a crash of the BT SDP dissector. This issue may allow a remote attacker to perform a DoS attack by consuming all available system resources, leading to excessive CPU resource consumption.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Amplification
An infinite loop will cause unexpected consumption of resources, such as CPU cycles or memory. The software's operation may slow down, or cause a long time to respond.
