CVE-2020-25866 (GCVE-0-2020-25866)

Vulnerability from cvelistv5 – Published: 2020-10-06 14:42 – Updated: 2024-08-04 15:49

Summary

In Wireshark 3.2.0 to 3.2.6 and 3.0.0 to 3.0.13, the BLIP protocol dissector has a NULL pointer dereference because a buffer was sized for compressed (not uncompressed) messages. This was addressed in epan/dissectors/packet-blip.c by allowing reasonable compression ratios and rejecting ZIP bombs.

Severity

No CVSS data available.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
