Summary
samba vulnerabilities
Details
Svyatoslav Phirsov discovered that the Samba libsmbclient library incorrectly handled extra long filenames. A malicious server could use this issue to cause Samba to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2018-10858)
Volker Mauel discovered that Samba incorrectly handled database output. When used as an Active Directory Domain Controller, a remote authenticated attacker could use this issue to cause Samba to crash, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-10918)
Phillip Kuhrt discovered that the Samba LDAP server incorrectly handled certain confidential attribute values. A remote authenticated attacker could possibly use this issue to obtain certain sensitive information. (CVE-2018-10919)
Vivek Das discovered that Samba incorrectly handled NTLMv1 being explicitly disabled on the server. A remote user could possibly be authenticated using NTLMv1, contrary to expectations. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-1139)

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.
