The smartcard interaction in SPICE allows remote attackers to cause a denial of service (QEMU-KVM process crash) or possibly execute arbitrary code via vectors related to connecting to a guest VM, which triggers a heap-based buffer overflow.

The ASN.1 implementation in OpenSSL before 1.0.1o and 1.0.2 before 1.0.2c allows remote attackers to execute arbitrary code or cause a denial of service (buffer underflow and memory corruption) via an ANY field in crafted serialized data, aka the "negative zero" issue.

Format string vulnerability in libxml2 before 2.9.4 allows attackers to have unspecified impact via format string specifiers in unknown vectors.

Heap-based buffer overflow in the unhtmlify function in foomatic-rip in foomatic-filters before 4.0.6 allows remote attackers to cause a denial of service (memory corruption and crash) or possibly execute arbitrary code via a long job title.

Integer overflow in the ftp_genlist function in ext/ftp/ftp.c in PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 allows remote FTP servers to execute arbitrary code via a long reply to a LIST command, leading to a heap-based buffer overflow. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-4022.

Heap-based buffer overflow in the PackBitsPreEncode function in tif_packbits.c in bmp2tiff in libtiff 4.0.6 and earlier allows remote attackers to execute arbitrary code or cause a denial of service via a large width field in a BMP image.

Stack-based buffer overflow in the munge_other_line function in cachemgr.cgi in the squid package before 3.1.23-16.el6_8.6 in Red Hat Enterprise Linux 6 allows remote attackers to execute arbitrary code via unspecified vectors. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-4051.

Heap-based buffer overflow in the xmlStrncat function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.

Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet.

objects.cc in Google V8 before 5.0.71.32, as used in Google Chrome before 51.0.2704.63, does not properly restrict lazy deoptimization, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted JavaScript code.

Use-after-free vulnerability in ports/SkFontHost_FreeType.cpp in Skia, as used in Google Chrome before 51.0.2704.63, allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via unknown vectors.

Heap-based buffer overflow in the opj_j2k_read_SPCod_SPCoc function in j2k.c in OpenJPEG, as used in PDFium in Google Chrome before 51.0.2704.63, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PDF document.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue.

The net_checksum_calculate function in net/checksum.c in QEMU allows local guest OS users to cause a denial of service (out-of-bounds heap read and crash) via the payload length in a crafted packet.

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.

The xmlNextChar function in libxml2 before 2.9.4 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.

Heap-based buffer overflow in SPICE before 0.12.6 allows guest OS users to cause a denial of service (heap-based memory corruption and QEMU-KVM crash) or possibly execute arbitrary code on the host via QXL commands related to the surface_id parameter.

Integer overflow in lib/asn1_decoder.c in the Linux kernel before 4.6 allows local users to gain privileges via crafted ASN.1 data.

Heap-based buffer overflow in the xmlFAParsePosCharGroup function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.

Integer overflow in the read_SubStreamsInfo function in archive_read_support_format_7zip.c in libarchive before 3.2.1 allows remote attackers to execute arbitrary code via a 7zip file with a large number of substreams, which triggers a heap-based buffer overflow.

Heap-based buffer overflow in the parse_codes function in archive_read_support_format_rar.c in libarchive before 3.2.1 allows remote attackers to execute arbitrary code via a RAR file with a zero-sized dictionary.

Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call.

Integer overflow in the opj_pi_create_decode function in pi.c in OpenJPEG allows remote attackers to execute arbitrary code via a crafted JP2 file, which triggers an out-of-bounds read or write.

numbers.c in libxslt before 1.1.29, as used in Google Chrome before 51.0.2704.63, mishandles namespace nodes, which allows remote attackers to cause a denial of service (out-of-bounds heap memory access) or possibly have unspecified other impact via a crafted document.
