ImageMagick 7.0.8-50 Q16 has a heap-based buffer over-read in MagickCore/fourier.c in ComplexImages.

http.c in Exiv2 through 0.27.1 allows a malicious http server to cause a denial of service (crash due to a NULL pointer dereference) by returning a crafted response that lacks a space character.

linker/linker.c in ToaruOS through 1.10.9 has insecure LD_LIBRARY_PATH handling in setuid applications.

kernel/sys/syscall.c in ToaruOS through 1.10.9 has incorrect access control in sys_sysfunc case 9 for TOARU_SYS_FUNC_SETHEAP, allowing arbitrary kernel pages to be mapped into user land, leading to root access.

kernel/sys/syscall.c in ToaruOS through 1.10.9 allows a denial of service upon a critical error in certain sys_sbrk allocation patterns (involving PAGE_SIZE, and a value less than PAGE_SIZE).

An integer wrap in kernel/sys/syscall.c in ToaruOS 1.10.10 allows users to map arbitrary kernel pages into userland process space via TOARU_SYS_FUNC_MMAP, leading to escalation of privileges.

apps/gsudo.c in gsudo in ToaruOS through 1.10.9 has a buffer overflow allowing local privilege escalation to the root user via the DISPLAY environment variable.

The Microsoft Security Response Center (MSRC) works to assess vulnerabilities that are externally reported to us as quickly as possible, but time can be lost if we have to confirm details of the repro steps or environment with the researcher to reproduce the vulnerability. Microsoft has made our “Time Travel Debugging” (TTD) tool publicly available to make it easy for security researchers to provide full repro, shortening investigations and potentially contributing to higher bounties (see “Report quality definitions for Microsoft’s Bug Bounty programs”).

In GraphicsMagick from version 1.3.8 to 1.4 snapshot-20190403 Q8, there is a heap-based buffer overflow in the function WritePDBImage of coders/pdb.c, which allows an attacker to cause a denial of service or possibly have unspecified other impact via a crafted image file. This is related to MagickBitStreamMSBWrite in magick/bit_stream.c.

In GraphicsMagick from version 1.3.30 to 1.4 snapshot-20190403 Q8, there is a heap-based buffer overflow in the function WriteMATLABImage of coders/mat.c, which allows an attacker to cause a denial of service or possibly have unspecified other impact via a crafted image file. This is related to ExportRedQuantumType in magick/export.c.
