Vulnerability Summary
Timeline
Description
linux-lts-utopic vulnerabilities It was discovered that a use-after-free vulnerability existed in the AF_UNIX implementation in the Linux kernel. A local attacker could use crafted epoll_ctl calls to cause a denial of service (system crash) or expose sensitive information. (CVE-2013-7446) It was discovered that the KVM implementation in the Linux kernel did not properly restore the values of the Programmable Interrupt Timer (PIT). A user-assisted attacker in a KVM guest could cause a denial of service in the host (system crash). (CVE-2015-7513) It was discovered that the Linux kernel keyring subsystem contained a race between read and revoke operations. A local attacker could use this to cause a denial of service (system crash). (CVE-2015-7550) Sasha Levin discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel had a race condition when checking whether a socket was bound or not. A local attacker could use this to cause a denial of service (system crash). (CVE-2015-7990) It was discovered that the Btrfs implementation in the Linux kernel incorrectly handled compressed inline extants on truncation. A local attacker could use this to expose sensitive information. (CVE-2015-8374) 郭永刚 discovered that the Linux kernel networking implementation did not validate protocol identifiers for certain protocol families, A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2015-8543) Dmitry Vyukov discovered that the pptp implementation in the Linux kernel did not verify an address length when setting up a socket. A local attacker could use this to craft an application that exposed sensitive information from kernel memory. (CVE-2015-8569) David Miller discovered that the Bluetooth implementation in the Linux kernel did not properly validate the socket address length for Synchronous Connection-Oriented (SCO) sockets. A local attacker could use this to expose sensitive information. (CVE-2015-8575)
