A null pointer dereference vulnerability was found in the function stackswap (called from decompileSTACKSWAP) in util/decompile.c in Ming 0.4.8, which allows attackers to cause a denial of service via a crafted file.

xen: possibly unbounded recursion in grant table code (XSA-226)

Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants.

xen: grant_table: Race conditions with maptrack free list handling (XSA-228)

Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling.

xen: x86: PV privilege escalation via map_grant_ref (XSA-227)

arch/x86/mm.c in Xen allows local PV guest OS users to gain host OS privileges via vectors related to map_grant_ref.

shadow-utils: Buffer overflow via newusers tool

In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts.

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.

Solr: Code execution via entity expansion

Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.

ImageMagick: Out-of-bounds read in ReadOneMNGImage function in coders/png.c

ImageMagick 7.0.6-1 has an out-of-bounds read vulnerability in ReadOneMNGImage in coders/png.c.

taglib: Incorrect cast in rebuildAggregateFrames function

In TagLib 1.11.1, the rebuildAggregateFrames function in id3v2framefactory.cpp has a pointer to cast vulnerability, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted audio file.

The InfoCard module 1.0 for SimpleSAMLphp allows attackers to spoof XML messages by leveraging an incorrect check of return values in signature validation utilities.

ImageMagick: Use-after-free vulnerability in the DestroyImage function

Use-after-free vulnerability in the DestroyImage function in image.c in ImageMagick before 7.0.6-6 allows remote attackers to cause a denial of service via a crafted file.

Improper Neutralization of Special Elements used in an OS Command in bookmarking function of Newsbeuter versions 0.7 through 2.9 allows remote attackers to perform user-assisted code execution by crafting an RSS item that includes shell code in its title and/or URL.

tcpdump: Buffer over-read in print-juniper.c:juniper_parse_header() in Juniper protocols parser

The Juniper protocols parser in tcpdump before 4.9.2 has a buffer over-read in print-juniper.c:juniper_parse_header().

GraphicsMagick 1.3.26 has a heap-based buffer overflow vulnerability in the function GetStyleTokens in coders/svg.c:314:12.

GraphicsMagick 1.3.26 has a heap-based buffer overflow vulnerability in the function GetStyleTokens in coders/svg.c:311:12.

GraphicsMagick 1.3.26 has a NULL pointer dereference vulnerability in the function SVGStartElement in coders/svg.c.
