https://notcve.org/view.php?id=CVE-2020-2756
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Serialization). Supported versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: Applies to client and server deployment of Java. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00048.html https://kc.mcafee.com/corporate/index?page=content&id=SB10332 https://lists.debian.org/debian-lts-announce/2020/04/msg00024.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CKAV6KFFAEANXAN73AFTGU7Z6YNRWCXQ https://lists.fedoraproject.org/archives& • CWE-248: Uncaught Exception CWE-502: Deserialization of Untrusted Data CWE-755: Improper Handling of Exceptional Conditions •

CVE-2020-5260 – malicious URLs may cause Git to present stored credentials to the wrong server
https://notcve.org/view.php?id=CVE-2020-5260
Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials to a host controlled by an attacker. Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that contain an encoded newline can inject unintended values into the credential helper protocol stream, causing the credential helper to retrieve the password for one server (e.g., good.example.com) for an HTTP request being made to another server (e.g., evil.example.com), resulting in credentials for the former being sent to the latter. There are no restrictions on the relationship between the two, meaning that an attacker can craft a URL that will present stored credentials for any host to a host of their choosing. The vulnerability can be triggered by feeding a malicious URL to git clone. • https://github.com/sv3nbeast/CVE-2020-5260 https://github.com/Asgavar/CVE-2020-5260 http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00003.html http://packetstormsecurity.com/files/157250/Git-Credential-Helper-Protocol-Newline-Injection.html http://www.openwall.com/lists/oss-security/2020/04/15/5 http://www.openwall.com/lists/oss-security/2020/04/15/6 http://www.openwall.com/lists/oss-security • CWE-20: Improper Input Validation CWE-522: Insufficiently Protected Credentials •
CVE-2020-11741
https://notcve.org/view.php?id=CVE-2020-11741
An issue was discovered in xenoprof in Xen through 4.13.x, allowing guest OS users (with active profiling) to obtain sensitive information about other guests, cause a denial of service, or possibly gain privileges. For guests for which "active" profiling was enabled by the administrator, the xenoprof code uses the standard Xen shared ring structure. Unfortunately, this code did not treat the guest as a potential adversary: it trusts the guest not to modify buffer size information or modify head / tail pointers in unexpected ways. This can crash the host (DoS). Privilege escalation cannot be ruled out. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00006.html http://www.openwall.com/lists/oss-security/2020/04/14/1 http://xenbits.xen.org/xsa/advisory-313.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5M2XRNCHOGGTJQBZQJ7DCV6ZNAKN3LE2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NVTP4OYHCTRU3ONFJOFJQVNDFB25KLLG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YMAW7D2MP • CWE-909: Missing Initialization of Resource •
