kernel: number wraparound vulnerability in function start_req()

Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel 2.6.x through 4.x before 4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large iov_count value in a write request.

The mysql-systemd-helper script in the mysql-community-server package before 5.6.28-2.17.1 in openSUSE 13.2 and before 5.6.28-13.1 in openSUSE Leap 42.1 and the mariadb package before 10.0.22-2.21.2 in openSUSE 13.2 and before 10.0.22-3.1 in SUSE Linux Enterprise (SLE) 12.1 and openSUSE Leap 42.1 allows local users to discover database credentials by listing a process and its arguments.

Qemu: ide: divide by zero issue

hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash.

glibc: getaddrinfo stack-based buffer overflow

Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module.

kernel: local privesc in key management

The KEYS subsystem in the Linux kernel before 4.4 allows local users to gain privileges or cause a denial of service (BUG) via crafted keyctl commands that negatively instantiate a key, related to security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and security/keys/user_defined.c.

xen: Linux pciback missing sanity checks leading to crash (XSA-157)

The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka "Linux pciback missing sanity checks."

glibc: Segmentation fault caused by passing out-of-range data to strftime()

The strftime function in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly obtain sensitive information via an out-of-range time value.

glibc: Integer overflow in hcreate and hcreate_r

Integer overflow in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via the size argument to the __hcreate_r function, which triggers out-of-bounds heap-memory access.

glibc: Unbounded stack allocation in catopen function

Stack-based buffer overflow in the catopen function in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long catalog name.

kernel: fuse: possible denial of service in fuse_fill_write_pages()

The fuse_fill_write_pages function in fs/fuse/file.c in the Linux kernel before 4.4 allows 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.

The DecodeImage function in coders/gif.c in GraphicsMagick 1.3.18 allows remote attackers to cause a denial of service (uninitialized memory access) via a crafted GIF file.

kernel: USB hub invalid memory access in hub_activate()

The hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device.

kernel: incorrect restoration of machine specific registers from userspace

The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application.

php: libxml_disable_entity_loader setting is shared between threads

ext/libxml/libxml.c in PHP before 5.5.22 and 5.6.x before 5.6.6, when PHP-FPM is used, does not isolate each thread from libxml_disable_entity_loader changes in other threads, which allows remote attackers to conduct XML External Entity (XXE) and XML Entity Expansion (XEE) attacks via a crafted XML document, a related issue to CVE-2015-5161.

libarchive: Unclear invalid memory read in mtree parser

The readline function in archive_read_support_format_mtree.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (invalid read) via a crafted mtree file, related to newline parsing.

libarchive: NULL pointer access in RAR parser

The archive_read_format_rar_read_data function in archive_read_support_format_rar.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (crash) via a crafted rar archive.

libarchive: Heap out of bounds read in mtree parser

The process_add_entry function in archive_read_support_format_mtree.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted mtree file.

libarchive: Memory leak in TAR parser

Memory leak in the __archive_read_get_extract function in archive_read_extract2.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service via a tar file.

libarchive: Undefined behavior (signed integer overflow) in mtree parser

Multiple integer overflows in the (1) get_time_t_max and (2) get_time_t_min functions in archive_read_support_format_mtree.c in libarchive before 3.2.0 allow remote attackers to have unspecified impact via a crafted mtree file, which triggers undefined behavior.
