There are several memory leaks in the MIFF coder in /coders/miff.c due to improper image depth values, which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact to application availability or cause a denial of service. It was originally reported that the issues were in `AcquireMagickMemory()` because that is where LeakSanitizer detected the leaks, but the patch resolves issues in the MIFF coder, which incorrectly handles data being passed to `AcquireMagickMemory()`. This flaw affects ImageMagick versions prior to 7.0.9-0.
ImageMagick 7.0.8-43 has a memory leak in coders/dot.c, as demonstrated by PingImage in MagickCore/constitute.c.

Memory leak in pngrutil.c in libpng before 1.2.44, and 1.4.x before 1.4.3, allows remote attackers to cause a denial of service (memory consumption and application crash) via a PNG image containing malformed Physical Scale (aka sCAL) chunks.
in SetImageExtent() of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because the code which checks for the proper image depth size does not reset the size in the event there is an invalid size. The patch resets the depth to a proper size before throwing an exception. The memory leak can be triggered by a crafted input file that is processed by ImageMagick and could cause an impact to application reliability, such as denial of service. This flaw affects ImageMagick versions prior to 7.0.9-0.
In ImageMagick 7.0.6-6, a memory leak vulnerability was found in the function WritePCXImage in coders/pcx.c, which allows attackers to cause a denial of service via a crafted file.
In coders/xbm.c in ImageMagick 7.0.6-1 Q16, a DoS in ReadXBMImage() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted XBM file, which claims large rows and columns fields in the header but does not contain sufficient backing data, is provided, the loop over the rows would consume huge CPU resources, since there is no EOF check inside the loop.
In ImageMagick 7.0.6-8, the WritePDFImage function in coders/pdf.c operates on an incorrect data structure in the "dump uncompressed PseudoColor packets" step, which allows attackers to cause a denial of service (assertion failure in WriteBlobStream in MagickCore/blob.c) via a crafted file.
In coders/ps.c in ImageMagick 7.0.7-0 Q16, a DoS in ReadPSImage() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted PSD file, which claims a large "extent" field in the header but does not contain sufficient backing data, is provided, the loop over "length" would consume huge CPU resources, since there is no EOF check inside the loop.
In the function ReadTXTImage() in coders/txt.c in ImageMagick 7.0.6-10, an integer overflow might occur for the addition operation "GetQuantumRange(depth)+1" when "depth" is large, producing a smaller value than expected. As a result, an infinite loop would occur for a crafted TXT file that claims a very large "max_value" value.
Out of bounds access in SwiftShader in Google Chrome prior to 73.0.3683.75 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
KsIRC 1.3.12 allows remote attackers to cause a denial of service (crash) via a long PRIVMSG string when connecting to an Internet Relay Chat (IRC) server, which causes an assertion failure and results in a NULL pointer dereference. NOTE: this issue was originally reported as a buffer overflow.
In ImageMagick 7.0.6-10, there is a heap-based buffer overflow in the TracePoint() function in MagickCore/draw.c.

In ImageMagick 7.0.6-10, a NULL Pointer Dereference issue is present in the ReadCUTImage function in coders/cut.c that could allow an attacker to cause a Denial of Service (in the QueueAuthenticPixelCacheNexus function within the MagickCore/cache.c file) by submitting a malformed image file.
In ImageMagick before 6.9.7-10, there is a crash (rather than a "width or height exceeds limit" error report) if the image dimensions are too large, as demonstrated by use of the mpc coder.

In ImageMagick 7.0.6-5, a length-validation vulnerability was found in the function ReadPSDLayersInternal in coders/psd.c, which allows attackers to cause a denial of service (ReadPSDImage memory exhaustion) via a crafted file.
The js_dtoa function in Mozilla Firefox 2.x before 2.0.0.1, 1.5.x before 1.5.0.9, Thunderbird before 1.5.0.9, and SeaMonkey before 1.0.7 overwrites memory instead of exiting when the floating point precision is reduced, which allows remote attackers to cause a denial of service via any plugins that reduce the precision.
softmagic.c in file before 5.17 and libmagic allows context-dependent attackers to cause a denial of service (out-of-bounds memory access and crash) via crafted offsets in the softmagic of a PE executable.
The gdImageCreateFromXpm function in gdxpm.c in libgd, as used in PHP 5.4.26 and earlier, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted color table in an XPM file.
In ImageMagick before 6.9.8-8 and 7.x before 7.0.5-9, the ReadJP2Image function in coders/jp2.c does not properly validate the channel geometry, leading to a crash.
