Design/Logic Flaw

A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions when the Samba VFS module "aclxattr" is configured with "aclxattr:ignore system acls = yes". The SMB protocol allows opening files when the client requests read-only acces...

Design/Logic Flaw

An out-of-bounds OOB memory read flaw was found in parseleasestate in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. When an attacker sends the CREATE command with a malformed payload to KSMBD, due to a missing check of NameOffset in the parseleasestate...

Design/Logic Flaw

A flaw was found in Samba. It is susceptible to a vulnerability where multiple incompatible RPC listeners can be initiated, causing disruptions in the AD DC service. When Samba's RPC server experiences a high load or unresponsiveness, servers intended for non-AD DC purposes for example,...

CVE-2023-4091

CVE-2023-4091 affects Samba, where the acl_xattr VFS module can allow an SMB client to truncate files to zero bytes even when opened with read-only access. This occurs when acl_xattr:ignore system acls = yes and the client uses an OVERWRITE create disposition, bypassing kernel permissions checks....
