ntp: crypto-NAK symmetric association authentication bypass vulnerability

Crypto-NAK packets in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to bypass authentication.

libavcodec/webp.c in FFmpeg before 2.8.12, 3.0.x before 3.0.8, 3.1.x before 3.1.8, 3.2.x before 3.2.5, and 3.3.x before 3.3.1 does not ensure that pix_fmt is set, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file, related to the vp8_decode_mb_row_no_filter and pred8x8_128_dc_8_c functions.

ntp: restriction list NULL pointer dereference

ntpd in NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (NULL pointer dereference) via a ntpdc reslist command.

FFmpeg before 2.8.12, 3.0.x and 3.1.x before 3.1.9, 3.2.x before 3.2.6, and 3.3.x before 3.3.2 does not properly restrict HTTP Live Streaming filename extensions and demuxer names, which allows attackers to read arbitrary files via crafted playlist data.

MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2, when a private wiki is configured, provides different error messages for failed login attempts depending on whether the username exists, which allows remote attackers to enumerate account names and conduct brute-force attacks via a series of requests.

In WordPress before 4.7.5, a cross-site scripting (XSS) vulnerability exists when attempting to upload very large files, because the error message does not properly restrict presentation of the filename.

opencv: out-of-bounds read error in the function icvCvt_BGRA2BGR_8u_C4C3R

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds read error in the function icvCvt_BGRA2BGR_8u_C4C3R when reading an image file by using cv::imread.

opencv: buffer overflow in the cv::BmpDecoder::readData function

OpenCV (Open Source Computer Vision Library) through 3.3 has a buffer overflow in the cv::BmpDecoder::readData function in modules/imgcodecs/src/grfmt_bmp.cpp when reading an image file by using cv::imread, as demonstrated by the 4-buf-overflow-readData-memcpy test case.

opencv: invalid write in the cv::RLByteStream::getBytes function

OpenCV (Open Source Computer Vision Library) through 3.3 has an invalid write in the cv::RLByteStream::getBytes function in modules/imgcodecs/src/bitstrm.cpp when reading an image file by using cv::imread, as demonstrated by the 2-opencv-heapoverflow-fseek test case.

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

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the FillUniColor function in utils.cpp when reading an image file by using cv::imread.

opencv: out-of-bounds write error in the function FillColorRow8

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the FillColorRow8 function in utils.cpp when reading an image file by using cv::imread.

opencv: out-of-bounds write error in the function FillColorRow4

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the function FillColorRow4 in utils.cpp when reading an image file by using cv::imread.

libreoffice: Out-of-bounds write in the PPTStyleSheet::PPTStyleSheet functionality

A vulnerability in OpenOffice's PPT file parser before 4.1.4, and specifically in PPTStyleSheet, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.

libreoffice: Out-of-bounds write in the WW8RStyle::ImportOldFormatStyles functionality

A vulnerability in Apache OpenOffice Writer DOC file parser before 4.1.4, and specifically in ImportOldFormatStyles, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.

opencv: out-of-bounds read error in the cv::RBaseStream::readBlock function

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds read error in the cv::RBaseStream::readBlock function in modules/imgcodecs/src/bitstrm.cpp when reading an image file by using cv::imread, as demonstrated by the 8-opencv-invalid-read-fread test case.

Deserialization vulnerability in lintian through 2.5.50.3 allows attackers to trigger code execution by requesting a review of a source package with a crafted YAML file.

In lrzip 0.631, a stack buffer overflow was found in the function get_fileinfo in lrzip.c:979, which allows attackers to cause a denial of service via a crafted file.

ghostscript: Heap-buffer over-read in the gs_alloc_ref_array function

The gs_alloc_ref_array function in psi/ialloc.c in Artifex Ghostscript 9.21 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document. This is related to a lack of an integer overflow check in base/gsalloc.c.

chromium-browser: out-of-bounds read in skia

Insufficient validation of untrusted input in Skia in Google Chrome prior to 60.0.3112.78 for Linux allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.

flatpak: Privilege escalation via setuid/world-writable file permissions

In Flatpak before 0.8.7, a third-party app repository could include malicious apps that contain files with inappropriate permissions, for example setuid or world-writable. The files are deployed with those permissions, which would let a local attacker run the setuid executable or write to the world-writable location. In the case of the "system helper" component, files deployed as part of the app are owned by root, so in the worst case they could be setuid root.
