opencv: out-of-bounds write error in the function FillColorRow1

OpenCV (Open Source Computer Vision Library) 3.3 has an out-of-bounds write error in the function FillColorRow1 in utils.cpp when reading an image file by using cv::imread. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-12597.

libarchive: Heap-based buffer over-read in the atol8 function

libarchive 3.3.2 allows remote attackers to cause a denial of service (xml_data heap-based buffer over-read and application crash) via a crafted xar archive, related to the mishandling of empty strings in the atol8 function in archive_read_support_format_xar.c.

Qemu: i386: multiboot OOB access while loading kernel image

Integer overflow in the load_multiboot function in hw/i386/multiboot.c in QEMU (aka Quick Emulator) allows local guest OS users to execute arbitrary code on the host via crafted multiboot header address values, which trigger an out-of-bounds write.

In the mxf_read_primer_pack function in libavformat/mxfdec.c in FFmpeg 3.3.3 -> 2.4, an integer signedness error might occur when a crafted file, which claims a large "item_num" field such as 0xffffffff, is provided. As a result, the variable "item_num" turns negative, bypassing the check for a large value.

libsndfile: Out-of-bounds read in the function d2alaw_array()

An out of bounds read in the function d2alaw_array() in alaw.c of libsndfile 1.0.28 may lead to a remote DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point values.

libsndfile: Out-of-bounds read in the function d2ulaw_array()

An out of bounds read in the function d2ulaw_array() in ulaw.c of libsndfile 1.0.28 may lead to a remote DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point values.

chromium-browser: heap buffer overflow in skia

Math overflow in Skia in Google Chrome prior to 61.0.3163.79 for Mac, Windows, and Linux, and 61.0.3163.81 for Android, allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

chromium-browser: url spoofing in omnibox

Insufficient Policy Enforcement in Omnibox in Google Chrome prior to 60.0.3112.78 for Mac, Windows, Linux, and Android allowed a remote attacker to perform domain spoofing via IDN homographs in a crafted domain name.

chromium-browser: url spoofing in omnibox

Insufficient Policy Enforcement in Omnibox in Google Chrome prior to 60.0.3112.78 for Mac, Windows, Linux, and Android allowed a remote attacker to perform domain spoofing via IDN homographs in a crafted domain name.

emacs: command injection flaw within "enriched mode" handling

GNU Emacs before 25.3 allows remote attackers to execute arbitrary code via email with crafted "Content-Type: text/enriched" data containing an x-display XML element that specifies execution of shell commands, related to an unsafe text/enriched extension in lisp/textmodes/enriched.el, and unsafe Gnus support for enriched and richtext inline MIME objects in lisp/gnus/mm-view.el. In particular, an Emacs user can be instantly compromised by reading a crafted email message (or Usenet news article).

dnsmasq: information leak in the DHCPv6 relay code

dnsmasq before 2.78, when configured as a relay, allows remote attackers to obtain sensitive memory information via vectors involving handling DHCPv6 forwarded requests.

dnsmasq: memory exhaustion vulnerability in the EDNS0 code

Memory leak in dnsmasq before 2.78, when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service (memory consumption) via vectors involving DNS response creation.

dnsmasq: integer underflow leading to buffer over-read in the EDNS0 code

Integer underflow in the add_pseudoheader function in dnsmasq before 2.78 , when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service via a crafted DNS request.

kernel: buffer overflow in tpacket_rcv() in net/packet/af_packet.c

The tpacket_rcv function in net/packet/af_packet.c in the Linux kernel before 4.13 mishandles vnet headers, which might allow local users to cause a denial of service (buffer overflow, and disk and memory corruption) or possibly have unspecified other impact via crafted system calls.

nautilus: Insufficient validation of trust of .desktop files with execute permission

GNOME Nautilus before 3.23.90 allows attackers to spoof a file type by using the .desktop file extension, as demonstrated by an attack in which a .desktop file's Name field ends in .pdf but this file's Exec field launches a malicious "sh -c" command. In other words, Nautilus provides no UI indication that a file actually has the potentially unsafe .desktop extension; instead, the UI only shows the .pdf extension. One (slightly) mitigating factor is that an attack requires the .desktop file to have execute permission. The solution is to ask the user to confirm that the file is supposed to be treated as a .desktop file, and then remember the user's answer in the metadata::trusted field.

ImageMagick: Out-of-bounds read in ReadTIFFImage in coders/tiff.c

In ImageMagick 7.0.7-4 Q16, an out of bounds read flaw related to ReadTIFFImage has been reported in coders/tiff.c. An attacker could possibly exploit this flaw to disclose potentially sensitive memory or cause an application crash.
