Details
Thijs Alkemade, Gustavo Grieco, Daniel Stenberg, and Nikos Mavrogiannopoulos discovered that Libidn incorrectly handled invalid UTF-8 characters. A remote attacker could use this issue to cause Libidn to crash, resulting in a denial of service, or possibly disclose sensitive memory. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-2059)
Hanno Böck discovered that Libidn incorrectly handled certain input. A remote attacker could possibly use this issue to cause Libidn to crash, resulting in a denial of service. (CVE-2015-8948, CVE-2016-6262, CVE-2016-6261, CVE-2016-6263)

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.
