8d4ee003b008842df1a8bbe4503c53d309960157148ffac1215331883d3d8291This Metasploit module exploits a serious flaw in Mac OS X High Sierra. Any user can login with user "root", leaving an empty password.
dd129338b035d1f1252020b0fcad4403a67d63fb88369b316e4ae2fb47bd5adcAnthony Perard discovered that the Xen virtual block driver did not properly initialize some data structures before passing them to user space. A local attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. Bo Zhang discovered that the netlink wireless configuration interface in the Linux kernel did not properly validate attributes when handling certain requests. A local attacker with the CAP_NET_ADMIN could use this to cause a denial of service (system crash). It was discovered that the nested KVM implementation in the Linux kernel in some situations did not properly prevent second level guests from reading and writing the hardware CR8 register. A local attacker in a guest could use this to cause a denial of service (system crash). Otto Ebeling discovered that the memory manager in the Linux kernel did not properly check the effective UID in some situations. A local attacker could use this to expose sensitive information.
4ac498fe64bdf58c75838bf98a75ded8239a7ff13c95ce564a4824dd91f56222Asterisk version 13.17.2~dfsg-2 suffers from a remote unauthenticated memory exhaustion vulnerability.
99d7d993e299b93cfe3175432dc128f681f04cd24bad4088cf2c8831bddb04c6Ubuntu Security Notice 3499-1 - It was discovered that Exim incorrectly handled certain BDAT data headers. A remote attacker could possibly use this issue to cause Exim to crash, resulting in a denial of service.
84f6e7318add2363801a7c087f557e0bfddc5858647315c8653fcfcb594b870eUbuntu Security Notice 3501-1 - It was discovered that libxcursor incorrectly handled certain files. An attacker could use these issues to cause libxcursor to crash, resulting in a denial of service, or possibly execute arbitrary code.
8533f39168f2a2d6205e712f40adfbaf90b4d8e07d352222a21441228524870dUbuntu Security Notice 3500-1 - It was discovered that libXfont incorrectly followed symlinks when opening font files. A local unprivileged user could use this issue to cause the X server to access arbitrary files, including special device files.
b53da59663327cdf80b5b7d9f88bd1b1f437c9713750218a9ffa0d56f2f3808fHipchat Data Center and Hipchat Server suffer from server-side request forgery and remote code execution vulnerabilities.
85ff28883c85d9d50aed28fb22e57f0ab765ebcb2f08baf9a4d008871ee54eb5Synology StorageManager version 5.2 suffers from a remote root command execution vulnerability in smart.cgi.
8b6426fb7ecab4c3be36761c437ebb2dc9019377c22d2acbac83d341781b3249Ubuntu Security Notice 3498-1 - Alex Nichols discovered that curl incorrectly handled NTLM authentication credentials. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 17.04 and Ubuntu 17.10. It was discovered that curl incorrectly handled FTP wildcard matching. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly obtain sensitive information. Various other issues were also addressed.
650767a44353568490e38105acd3e0afe1602b6c2b58241f68d62f5dae049444Ubuntu Security Notice 3497-1 - It was discovered that the Smart Card IO subsystem in OpenJDK did not properly maintain state. An attacker could use this to specially construct an untrusted Java application or applet to gain access to a smart card, bypassing sandbox restrictions. Gaston Traberg discovered that the Serialization component of OpenJDK did not properly limit the amount of memory allocated when performing deserializations. An attacker could use this to cause a denial of service. Various other issues were also addressed.
5b6e1cbb08aebbd2d544357da18dc70e489442ccb7b7c6b9b67ccfd975ff3593Red Hat Security Advisory 2017-3278-01 - Samba is an open-source implementation of the Server Message Block or Common Internet File System protocol, which allows PC-compatible machines to share files, printers, and other information. Security Fix: A use-after-free flaw was found in the way samba servers handled certain SMB1 requests. An unauthenticated attacker could send specially-crafted SMB1 requests to cause the server to crash or execute arbitrary code.
de1f8ce0c545dd5e721901bd69c8576b25fd91fc7c1a1fc6417acc89c997fbbdRed Hat Security Advisory 2017-3277-01 - The tcmu-runner packages provide a service that handles the complexity of the LIO kernel target's userspace passthrough interface. It presents a C plugin API for extension modules that handle SCSI requests in ways not possible or suitable to be handled by LIO's in-kernel backstores. Security Fix: A flaw was found in the implementation of CheckConfig method in handler_glfs.so of the tcmu-runner daemon. A local, non-root user with access to the D-Bus system bus could send a specially crafted string to CheckConfig method resulting in various kinds of segmentation fault.
