F5 Networks BIG-IP : Samba vulnerabilities (K37603172) (Badlock)
Medium Nessus Plugin ID 91055
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionCVE-2015-5370 Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not properly implement the DCE-RPC layer, which allows remote attackers to perform protocol-downgrade attacks, cause a denial of service (application crash or CPU consumption), or possibly execute arbitrary code on a client system via unspecified vectors.
CVE-2016-2118 The MS-SAMR and MS-LSAD protocol implementations in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 mishandle DCERPC connections, which allows man-in-the-middle attackers to perform protocol-downgrade attacks and impersonate users by modifying the client-server data stream, aka 'BADLOCK.'
