Artifex Ghostscript through 2017-04-26 allows -dSAFER bypass and remote command execution via .rsdparams type confusion with a "/OutputFile (%pipe%" substring in a crafted .eps document that is an input to the gs program, as exploited in the wild in April 2017.

A trivial sandbox (enabled with the `-dSAFER` option) escape flaw was found in the ghostscript interpreter by injecting a specially crafted pipe command. This flaw allows a specially crafted document to execute arbitrary commands on the system in the context of the ghostscript…

In MuJS before version 1.1.2, a use-after-free flaw in the regexp source property access may cause denial of service.

A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then…

An issue was discovered in Artifex Ghostscript before 10.05.0. Access to arbitrary files can occur through a truncated path with invalid UTF-8 characters, for base/gp_mswin.c and base/winrtsup.cpp.

An issue was discovered in Artifex Ghostscript before 10.05.0. The BJ10V device has a Print buffer overflow in contrib/japanese/gdev10v.c.

An issue was discovered in Artifex Ghostscript before 10.05.0. The NPDL device has a Compression buffer overflow for contrib/japanese/gdevnpdl.c.

An issue was discovered in Artifex Ghostscript before 10.05.0. The DOCXWRITE TXTWRITE device has a text buffer overflow via long characters to devices/vector/doc_common.c.

Buffer-overflow in jsdtoa.c in Artifex MuJS in versions 1.0.1 to 1.1.1. An integer overflow happens when js_strtod() reads in floating point exponent, which leads to a buffer overflow in the pointer *d.

In Artifex Ghostscript through 10.01.0, there is a buffer overflow leading to potential corruption of data internal to the PostScript interpreter, in base/sbcp.c. This affects BCPEncode, BCPDecode, TBCPEncode, and TBCPDecode. If the write buffer is filled to one byte less than…

Artifex MuJS v1.1.3 was discovered to contain a heap buffer overflow which is caused by conflicting JumpList of nested try/finally statements.

A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max…

jbig2_image_compose in jbig2_image.c in Artifex jbig2dec before 0.18 has a heap-based buffer overflow.

An issue was discovered in Artifex MuJS 1.0.5. regcompx in regexp.c does not restrict regular expression program size, leading to an overflow of the parsed syntax list size.

An issue was discovered in Artifex MuJS 1.0.5. The Number#toFixed() and numtostr implementations in jsnumber.c have a stack-based buffer overflow.

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

Ghostscript before 9.21 might allow remote attackers to bypass the SAFER mode protection mechanism and consequently execute arbitrary code by leveraging type confusion in .initialize_dsc_parser.

Use-after-free vulnerability in Ghostscript 9.20 might allow remote attackers to execute arbitrary code via vectors related to a reference leak in .setdevice.

Heap-based buffer overflow in the js_stackoverflow function in jsrun.c in Artifex Software, Inc. MuJS allows attackers to have unspecified impact by leveraging an error when dropping extra arguments to lightweight functions.

An integer overflow vulnerability was observed in the regemit function in regexp.c in Artifex Software, Inc. MuJS before fa3d30fd18c348bb4b1f3858fb860f4fcd4b2045. The attack requires a regular expression with nested repetition. A successful exploitation of this issue can lead to…
