Artifex Ghostscript

gs_lib_ctx_stash_sanitized_arg in base/gslibctx.c in Artifex Ghostscript before 10.05.1 lacks argument sanitization for the # case. A created PDF document includes its password in cleartext.

In Artifex Ghostscript before 10.05.0, decode_utf8 in base/gp_utf8.c mishandles overlong UTF-8 encoding. NOTE: this issue exists because of an incomplete fix for CVE-2024-46954.

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. A buffer overflow occurs when converting glyphs to Unicode in psi/zbfont.c.

An issue was discovered in Artifex Ghostscript before 10.05.0. A buffer overflow occurs via an oversized Type 4 function in a PDF document to pdf/pdf_func.c.

An issue was discovered in Artifex Ghostscript before 10.05.0. A buffer overflow occurs for a long TTF font name to pdf/pdf_fmap.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.

An issue was discovered in Artifex Ghostscript before 10.05.0. A buffer overflow occurs during serialization of DollarBlend in a font, for base/write_t1.c and psi/zfapi.c.

An issue was discovered in psi/zfile.c in Artifex Ghostscript before 10.04.0. Out-of-bounds data access in filenameforall can lead to arbitrary code execution.

An issue was discovered in psi/zcolor.c in Artifex Ghostscript before 10.04.0. There is an out-of-bounds read when reading color in Indexed color space.

An issue was discovered in decode_utf8 in base/gp_utf8.c in Artifex Ghostscript before 10.04.0. Overlong UTF-8 encoding leads to possible ../ directory traversal.

An issue was discovered in base/gsdevice.c in Artifex Ghostscript before 10.04.0. An integer overflow when parsing the filename format string (for the output filename) results in path truncation, and possible path traversal and code execution.

An issue was discovered in pdf/pdf_xref.c in Artifex Ghostscript before 10.04.0. There is a buffer overflow during handling of a PDF XRef stream (related to W array values).

An issue was discovered in psi/zcolor.c in Artifex Ghostscript before 10.04.0. An unchecked Implementation pointer in Pattern color space could lead to arbitrary code execution.

An issue was discovered in Artifex Ghostscript before 10.03.1. contrib/opvp/gdevopvp.c allows arbitrary code execution via a custom Driver library, exploitable via a crafted PostScript document. This occurs because the Driver parameter for opvp (and oprp) devices can have an arbitrary name for a dynamic library; this library is then loaded.

An issue was discovered in Artifex Ghostscript before 10.03.1. There is path traversal (via a crafted PostScript document) to arbitrary files if the current directory is in the permitted paths. For example, there can be a transformation of ../../foo to ./../../foo and this will grant access if ./ is permitted.

An issue was discovered in Artifex Ghostscript before 10.03.1. Path traversal and command execution can occur (via a crafted PostScript document) because of path reduction in base/gpmisc.c. For example, restrictions on use of %pipe% can be bypassed via the aa/../%pipe%command# output filename.

Artifex Ghostscript before 10.03.1, when Tesseract is used for OCR, has a directory traversal issue that allows arbitrary file reading (and writing of error messages to arbitrary files) via OCRLanguage. For example, exploitation can use debug_file /tmp/out and user_patterns_file /etc/passwd.

Artifex Ghostscript before 10.03.1 allows memory corruption, and SAFER sandbox bypass, via format string injection with a uniprint device.

Artifex Ghostscript before 10.03.0 has a heap-based overflow when PDFPassword (e.g., for runpdf) has a \000 byte in the middle.

Artifex Ghostscript before 10.03.0 has a heap-based pointer disclosure (observable in a constructed BaseFont name) in the function pdf_base_font_alloc.

Artifex Ghostscript before 10.03.0 sometimes has a stack-based buffer overflow via the CIDFSubstPath and CIDFSubstFont parameters.

Artifex Ghostscript before 10.03.0 has a stack-based buffer overflow in the pdfi_apply_filter() function via a long PDF filter name.
