| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2016-04-25 | CVE-2016-2115 | 7PK - Security Features vulnerability in multiple products 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 require SMB signing within a DCERPC session over ncacn_np, which allows man-in-the-middle attackers to spoof SMB clients by modifying the client-server data stream. | 4.3 |
| 2016-04-25 | CVE-2016-2114 | 7PK - Security Features vulnerability in multiple products The SMB1 protocol implementation in Samba 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not recognize the "server signing = mandatory" setting, which allows man-in-the-middle attackers to spoof SMB servers by modifying the client-server data stream. | 4.3 |
| 2016-04-25 | CVE-2016-2113 | Cryptographic Issues vulnerability in multiple products Samba 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not verify X.509 certificates from TLS servers, which allows man-in-the-middle attackers to spoof LDAPS and HTTPS servers and obtain sensitive information via a crafted certificate. | 5.8 |
| 2016-04-25 | CVE-2016-2112 | 7PK - Security Features vulnerability in multiple products The bundled LDAP client library 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 does not recognize the "client ldap sasl wrapping" setting, which allows man-in-the-middle attackers to perform LDAP protocol-downgrade attacks by modifying the client-server data stream. | 4.3 |
| 2016-04-25 | CVE-2016-2111 | 7PK - Security Features vulnerability in multiple products The NETLOGON service 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, when a domain controller is configured, allows remote attackers to spoof the computer name of a secure channel's endpoint, and obtain sensitive session information, by running a crafted application and leveraging the ability to sniff network traffic, a related issue to CVE-2015-0005. | 4.3 |
| 2016-04-25 | CVE-2016-2110 | 7PK - Security Features vulnerability in multiple products The NTLMSSP authentication implementation 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 allows man-in-the-middle attackers to perform protocol-downgrade attacks by modifying the client-server data stream to remove application-layer flags or encryption settings, as demonstrated by clearing the NTLMSSP_NEGOTIATE_SEAL or NTLMSSP_NEGOTIATE_SIGN option to disrupt LDAP security. | 4.3 |
| 2016-04-25 | CVE-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. | 4.3 |
| 2016-04-21 | CVE-2013-7449 | Cryptographic Issues vulnerability in multiple products The ssl_do_connect function in common/server.c in HexChat before 2.10.2, XChat, and XChat-GNOME does not verify that the server hostname matches a domain name in the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. | 5.8 |
| 2016-04-21 | CVE-2016-0642 | Unspecified vulnerability in Oracle MySQL 5.5.48 and earlier, 5.6.29 and earlier, and 5.7.11 and earlier allows local users to affect integrity and availability via vectors related to Federated. | 4.3 |
| 2016-04-20 | CVE-2015-7802 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products gifread.c in gif2png, as used in OptiPNG before 0.7.6, allows remote attackers to cause a denial of service (uninitialized memory read) via a crafted GIF file. | 4.3 |
