Artifex Ghostscript any version

A null pointer dereference vulnerability in compose_group_nonknockout_nonblend_isolated_allmask_common() in base/gxblend.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use incorrect access checking in temp file handling to disclose contents of files on the system otherwise not readable.

In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use incorrect free logic in pagedevice replacement to crash the interpreter.

Ghostscript GhostPDL 9.50 through 9.54.0 has a heap-based buffer overflow in sampled_data_finish (called from sampled_data_continue and interp).

Ghostscript GhostPDL 9.50 through 9.53.3 has a use-after-free in sampled_data_sample (called from sampled_data_continue and interp).

Ghostscript: out-of-bound read in base/gdevdevn.c:1973 in devn_pcx_write_rle could result in dos

Ghostscript: incomplete fix for cve-2020-16305

An issue was discovered in Artifex Ghostscript before 10.03.1. psi/zmisc1.c, when SAFER mode is used, allows eexec seeds other than the Type 1 standard.

Ghostscript: integer overflow in pcl/pl/plfont.c:418 in pl_glyph_name

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.

Artifex Ghostscript through 10.05.1 has a stack-based buffer overflow in pdf_write_cmap in devices/vector/gdevpdtw.c.

Artifex Ghostscript through 10.05.1 has a stack-based buffer overflow in pdfmark_coerce_dest in devices/vector/gdevpdfm.c via a large size value.

In Artifex Ghostscript through 10.05.1, ocr_begin_page in devices/gdevpdfocr.c has an integer overflow that leads to a heap-based buffer overflow in ocr_line8.

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

psi/zfile.c in Artifex Ghostscript before 9.21rc1 permits the status command even if -dSAFER is used, which might allow remote attackers to determine the existence and size of arbitrary files, a similar issue to CVE-2016-7977.

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.

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.

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.

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.
