ID CVE-2015-8787
Summary The nf_nat_redirect_ipv4 function in net/netfilter/nf_nat_redirect.c in the Linux kernel before 4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by sending certain IPv4 packets to an incompletely configured interface, a related issue to CVE-2003-1604.

    description The openSUSE Leap 42.1 kernel was updated to 4.1.20 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-1339: A memory leak in cuse could be used to exhaust kernel memory. (bsc#969356). - CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel did not ensure that certain slot numbers are valid, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call (bnc#949936 951638). - CVE-2015-7872: The key_gc_unused_keys function in security/keys/gc.c in the Linux kernel allowed local users to cause a denial of service (OOPS) via crafted keyctl commands (bnc#951440). - CVE-2015-7884: The vivid_fb_ioctl function in drivers/media/platform/vivid/vivid-osd.c in the Linux kernel did not initialize a certain structure member, which allowed local users to obtain sensitive information from kernel memory via a crafted application (bnc#951626). - CVE-2015-8104: The KVM subsystem in the Linux kernel allowed guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c (bnc#954404). - CVE-2015-8709: kernel/ptrace.c in the Linux kernel mishandled uid and gid mappings, which allowed local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call. NOTE: the vendor states 'there is no kernel bug here (bnc#959709). - CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux kernel did not properly manage the relationship between a lock and a socket, which allowed local users to cause a denial of service (deadlock) via a crafted sctp_accept call. (bsc#961509) - CVE-2015-8785: The fuse_fill_write_pages function in fs/fuse/file.c in the Linux kernel allowed local users to cause a denial of service (infinite loop) via a writev system call that triggers a zero length for the first segment of an iov (bnc#963765). - CVE-2015-8787: The nf_nat_redirect_ipv4 function in net/netfilter/nf_nat_redirect.c in the Linux kernel allowed remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by sending certain IPv4 packets to an incompletely configured interface, a related issue to CVE-2003-1604 (bnc#963931). - CVE-2015-8812: A flaw was found in the CXGB3 kernel driver when the network was considered congested. The kernel would incorrectly misinterpret the congestion as an error condition and incorrectly free/clean up the skb. When the device would then send the skb's queued, these structures would be referenced and may panic the system or allow an attacker to escalate privileges in a use-after-free scenario. (bsc#966437). - CVE-2016-0723: Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call (bnc#961500). - CVE-2016-2069: When Linux invalidated a paging structure that is not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. (bsc#963767) - CVE-2016-2184: A malicious USB device could cause a kernel crash in the alsa usb-audio driver. (bsc#971125) - CVE-2016-2383: Incorrect branch fixups for eBPF allow arbitrary read of kernel memory. (bsc#966684) - CVE-2016-2384: A malicious USB device could cause a kernel crash in the alsa usb-audio driver.

CONFIG_DDR is selected automatically by drivers which need it. - config: Disable MFD_TPS65218 The TPS65218 is a power management IC for 32-bit ARM systems. - config: Modularize NF_REJECT_IPV4/V6 There is no reason why these helper modules should be built-in when the rest of netfilter is built as modules. - config: Update x86 config files: Enable Intel RAPL This driver is useful when power caping is needed. It was enabled in the SLE kernel 2 years ago. - Delete patches.fixes/bridge-module-get-put.patch.

    description A race condition in the IPC object implementation in the Linux kernel through 4.2.3 allows local users to gain privileges by triggering an ipc_addid call that leads to uid and gid comparisons against uninitialized data, related to msg.c, shm.c, and util.c. (CVE-2015-7613) Linux kernels built with the name spaces support(CONFIG_NAMESPACE) is vulnerable to a potential privilege escalation flaw. It could occur when a process within a container escapes the intended bind mounts to access the full file system. A privileged user inside a container could use this flaw to potentially gain full privileges on a system. (CVE-2015-2925) A NULL pointer dereference vulnerability was found in the Linux kernel's TCP stack, in net/netfilter/nf_nat_redirect.c in the nf_nat_redirect_ipv4() function. A remote, unauthenticated user could exploit this flaw to create a system crash (denial of service). (CVE-2015-8787)

(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) It was discovered that the netfilter Network Address Translation (NAT) implementation did not ensure that data structures were initialized when handling IPv4 addresses. An attacker could use this to cause a denial of service (system crash). (CVE-2015-8787). 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.
