USN-3291-1

Summary: linux vulnerabilities

Details: Dmitry Vyukov discovered that the generic SCSI (sg) subsystem in the Linux kernel contained a stack-based buffer overflow. A local attacker with access to an sg device could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7187) It was discovered that a NULL pointer dereference existed in the Direct Rendering Manager (DRM) driver for VMWare devices in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-7261) Li Qiang discovered that an integer overflow vulnerability existed in the Direct Rendering Manager (DRM) driver for VMWare devices in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7294) It was discovered that an information leak existed in the set_mempolicy and mbind compat syscalls in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-7616)
