jsparse.c in Artifex MuJS through 1.0.2 does not properly maintain the AST depth for binary expressions, which allows remote attackers to cause a denial of service (excessive recursion) via a crafted file.

In MuPDF 1.12.0, there is an infinite loop vulnerability and application hang in the pdf_parse_array function (pdf/pdf-parse.c) because EOF is not considered. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted pdf file.

In Artifex MuPDF 1.14.0, the svg_run_image function in svg/svg-run.c allows remote attackers to cause a denial of service (href_att NULL pointer dereference and application crash) via a crafted svg file, as demonstrated by mupdf-gl.

In Artifex MuPDF 1.14.0, svg/svg-run.c allows remote attackers to cause a denial of service (recursive calls followed by a fitz/xml.c fz_xml_att crash from excessive stack consumption) via a crafted svg file, as demonstrated by mupdf-gl.

In Artifex MuPDF 1.14.0, there is an infinite loop in the function svg_dev_end_tile in fitz/svg-device.c, as demonstrated by mutool.

ghostscript: Attempting to open a carefully crafted PDF file results in long-running computation (699856)

In Artifex Ghostscript before 9.26, a carefully crafted PDF file can trigger an extremely long running computation when parsing the file.

ghostscript: access bypass in psi/zfjbig2.c (700168)

psi/zfjbig2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because of a JBIG2Decode type confusion.

ghostscript: access bypass in psi/zicc.c (700169)

psi/zicc.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because of a setcolorspace type confusion.

ghostscript: access bypass in psi/zdevice2.c (700153)

psi/zdevice2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because available stack space is not checked when the device remains the same.

ghostscript: Improperly implemented security check in zsetdevice function in psi/zdevice.c

An issue was discovered in Artifex Ghostscript before 9.26. LockSafetyParams is not checked correctly if another device is used.

ghostscript: Type confusion in setpattern (700141)

In Artifex Ghostscript through 9.25, the setpattern operator did not properly validate certain types. A specially crafted PostScript document could exploit this to crash Ghostscript or, possibly, execute arbitrary code in the context of the Ghostscript process. This is a type confusion issue because of failure to check whether the Implementation of a pattern dictionary was a structure type.

There is an out-of-bounds read in fz_run_t3_glyph in fitz/font.c in Artifex MuPDF 1.14.0, as demonstrated by mutool.

ghostscript: 1Policy operator allows a sandbox protection bypass

Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving the 1Policy operator.

ghostscript: Saved execution stacks can leak operator arrays

Artifex Ghostscript allows attackers to bypass a sandbox protection mechanism by leveraging exposure of system operators in the saved execution stack in an error object.

ghostscript: Saved execution stacks can leak operator arrays (incomplete fix for CVE-2018-17183)

Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving errorhandler setup. NOTE: this issue exists because of an incomplete fix for CVE-2018-17183.

ghostscript: User-writable error exception table

Artifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code.

ghostscript: incomplete fix for CVE-2018-16509

It was found that RHSA-2018:2918 did not fully fix CVE-2018-16509. An attacker could possibly exploit another variant of the flaw and bypass the -dSAFER protection to, for example, execute arbitrary shell commands via a specially crafted PostScript document. This only affects ghostscript 9.07 as shipped with Red Hat Enterprise Linux 7.

ghostscript: Incorrect "restoration of privilege" checking when running out of stack during exception handling

An issue was discovered in Artifex Ghostscript before 9.25. Incorrect "restoration of privilege" checking when running out of stack during exception handling could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction. This is due to an incomplete fix for CVE-2018-16509.

In Artifex MuPDF 1.13.0, the fz_append_byte function in fitz/buffer.c allows remote attackers to cause a denial of service (segmentation fault) via a crafted pdf file. This is caused by a pdf/pdf-device.c pdf_dev_alpha array-index underflow.

In Artifex MuPDF 1.13.0, the pdf_get_xref_entry function in pdf/pdf-xref.c allows remote attackers to cause a denial of service (segmentation fault in fz_write_data in fitz/output.c) via a crafted pdf file.
