Summary
samba vulnerabilities
Details

It was discovered that Samba incorrectly handled Winbind NTLM authentication responses. An attacker could possibly use this issue to cause Samba to crash, resulting in a denial of service. (CVE-2022-2127)

Andreas Schneider discovered that Samba incorrectly enforced SMB2 packet signing. A remote attacker could possibly use this issue to obtain or modify sensitive information. This issue only affected Ubuntu 23.04. (CVE-2023-3347)

Florent Saudel and Arnaud Gatignolof discovered that Samba incorrectly handled certain Spotlight requests. A remote attacker could possibly use this issue to cause Samba to consume resources, leading to a denial of service. (CVE-2023-34966, CVE-2023-34967)

Ralph Boehme and Stefan Metzmacher discovered that Samba incorrectly handled paths returned by Spotlight requests. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2023-34968)
