Artifex MuPDF before 1.18.0 has a heap based buffer over-write in tiff_expand_colormap() function when parsing TIFF files allowing attackers to cause a denial of service.
A flaw was found in mupdf 1.18.0. Double free of object during linearization may lead to memory corruption and other potential consequences.
A Use After Free vulnerability exists in Artifex Software, Inc. MuPDF library 1.17.0-rc1 and earlier when a valid page was followed by a page with invalid pixmap dimensions, causing bander - a static - to point to previously freed memory instead of a newband_writer.
Artifex MuPDF before 1.18.0 has a heap based buffer over-write when parsing JBIG2 files allowing attackers to cause a denial of service.
SumatraPDF 2.1.1/MuPDF 1.0 allows remote attackers to cause an Integer Overflow in the lex_number() function via a corrupt PDF file.

Artifex MuPDF 1.15.0 has a heap-based buffer overflow in fz_append_display_node located at fitz/list-device.c, allowing remote attackers to execute arbitrary code via a crafted PDF file. This occurs with a large BDC property name that overflows the allocated size of a display list node.
Usage of an uninitialized variable in the function fz_load_jpeg in Artifex MuPDF 1.14 can result in a heap overflow vulnerability that allows an attacker to execute arbitrary code.
