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

The gx_ttfReader__Read function in base/gxttfb.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document.

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

The Ins_JMPR function in base/ttinterp.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document.

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

The xps_decode_font_char_imp function in xps/xpsfont.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document.

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.

libdwarf: Heap-based buffer overflow in update_entry()

The WRITE_UNALIGNED function in dwarf_elf_access.c in libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds write and crash) via a crafted DWARF section.

A heap-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to the heap-based buffer, which could allow an attacker to execute arbitrary code under the context of the process.

perl: Heap buffer overflow in regular expression compiler

Heap-based buffer overflow in the S_regatom function in regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 allows remote attackers to cause a denial of service (out-of-bounds write) via a regular expression with a '\N{}' escape and the case-insensitive modifier.

opencv: Heap-based buffer over-write in modules/imgcodecs/src/grfmt_pxm.cpp

In modules/imgcodecs/src/grfmt_pxm.cpp, the length of buffer AutoBuffer _src is small than expected, which will cause copy buffer overflow later. If the image is from remote, may lead to remote code execution or denial of service. This affects Opencv 3.3 and earlier.

ImageMagick: Heap-based buffer overflow in enhance.c

Heap-based buffer overflow in enhance.c in ImageMagick before 7.0.6-6 allows remote attackers to cause a denial of service via a crafted file.

exiv2: Heap-based buffer overflow in basicio.cpp

There is a heap-based buffer overflow in basicio.cpp of Exiv2 0.26. The vulnerability causes an out-of-bounds write in Exiv2::Image::printIFDStructure(), which may lead to remote denial of service or possibly unspecified other impact.

exiv2: Heap-based buffer over-read in Exiv2::Image::io function

There is a heap-based buffer over-read in libexiv2 in Exiv2 0.26 that is triggered in the Exiv2::Image::io function in image.cpp. It will lead to remote denial of service.

ImageMagick: Heap-based buffer overflow in the ReadSFWImage function

Heap-based buffer overflow in the ReadSFWImage function in coders/sfw.c in ImageMagick 7.0.6-8 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file.

GNU Wget: heap overflow in HTTP protocol handling

The retr.c:fd_read_body() function is called when processing OK responses. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to read the chunk in pieces of 8192 bytes by using the MIN() macro, but ends up passing the negative chunk length to retr.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument. The attacker can corrupt malloc metadata after the allocated buffer.

liblouis: Heap-buffer overflow resulting in an out-of-bounds write in resolveSubtable() function

There is a heap-based buffer overflow that causes a more than two thousand bytes out-of-bounds write in Liblouis 3.2.0, triggered in the function resolveSubtable() in compileTranslationTable.c. It will lead to denial of service or remote code execution.
