    description This update fixes the CVEs described below. CVE-2013-7446 Dmitry Vyukov discovered that a particular sequence of valid operations on local (AF_UNIX) sockets can result in a use-after-free. This may be used to cause a denial of service (crash) or possibly for privilege escalation. CVE-2015-7799 郭永刚 discovered that a user granted access to /dev/ppp can cause a denial of service (crash) by passing invalid parameters to the PPPIOCSMAXCID ioctl. This also applies to ISDN PPP device nodes. CVE-2015-7833 Sergej Schumilo, Hendrik Schwartke and Ralf Spenneberg discovered a flaw in the processing of certain USB device descriptors in the usbvision driver. An attacker with physical access to the system can use this flaw to crash the system. CVE-2015-7990 It was discovered that the fix for CVE-2015-6937 was incomplete. A race condition when sending a message on unbound socket can still cause a NULL pointer dereference. A remote attacker might be able to cause a denial of service (crash) by sending a crafted packet. CVE-2015-8324 'Valintinr' reported that an attempt to mount a corrupted ext4 filesystem may result in a kernel panic. A user permitted to mount filesystems could use this flaw to crash the system. For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze17. We recommend that you upgrade your linux-2.6 packages. For the oldstable (wheezy) and stable (jessie) distributions, CVE-2015-7833, CVE-2015-7990 and CVE-2015-8324 have been fixed and the other issues will be fixed soon.

    description 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) Guoyong Gang 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). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description 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) 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). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description The remote Debian host is running a version of the Linux kernel prior to 3.2.73-2+deb7u1 on Debian 7 or is running a version of the Linux kernel prior to 3.16.7-ckt20-1+deb8u1 on Debian 8. It is, therefore, affected by the following vulnerabilities : - A use-after-free error exists in the unix_dgram_poll() function within file net/unix/af_unix.c. A local attacker can exploit this, via specially crafted epoll_ctl calls, to cause a denial of service condition or bypass AF_UNIX socket permissions. (CVE-2013-7446) - A NULL pointer dereference flaw exists in the slhc_init() function within file drivers/net/slip/slhc.c due to improper validation of slot numbers. A local attacker can exploit this, via specially crafted PPPIOCSMAXCID IOCTL calls, to cause a denial of service condition. (CVE-2015-7799) - A flaw exists in the usbvision driver that allows a local attacker, via a nonzero bInterfaceNumber value in a USB device descriptor, to cause a kernel panic, resulting in a denial of service condition. (CVE-2015-7833) - An infinite loop condition exists in the KVM subsystem on some unspecified CPU chipsets. A local attacker who has sufficient privileges within a virtual guest OS can exploit this issue, by triggering many debug exceptions, to cause a denial of service condition. (CVE-2015-8104) - A flaw exists in the truncate_space_check() function within file /fs/btrfs/inode.c due to improper handling of compressed file extents. A local attacker can exploit this, via a clone action, to disclose sensitive pre-truncation information from a file. (CVE-2015-8374) - A NULL pointer dereference flaw exists in the inet_autobind() function within file net/ipv4/af_inet.c when handling connection attempts via IPv6. A local attacker can exploit this, via a specially crafted SOCK_RAW application that makes use of CLONE_NEWUSER support, to cause a denial of service condition or possibly gain elevated privileges. (CVE-2015-8543)
