Vulnerabilities (CVE)

A buffer overflow vulnerability in contrib/gdevdj9.c of Artifex Software GhostScript v9.18 to 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 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 full, and one then tries to write an escaped character, two bytes are written.

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.

Artifex Ghostscript through 10.01.2 mishandles permission validation for pipe devices (with the %pipe% prefix or the | pipe character prefix).

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

A floating point exception (divide-by-zero) vulnerability was discovered in Artifex MuPDF 1.23.4 in functon compute_color() of jquant2.c. NOTE: this is disputed by the supplier because there was not reasonable evidence to determine the existence of a vulnerability or identify the affected product.

A floating point exception (divide-by-zero) vulnerability was discovered in mupdf 1.23.4 in function pnm_binary_read_image() of load-pnm.c when fz_colorspace_n returns zero.

A floating point exception (divide-by-zero) vulnerability was discovered in Artifex MuPDF 1.23.4 in function bmp_decompress_rle4() of load-bmp.c.

A floating point exception (divide-by-zero) vulnerability was discovered in Artifex MuPDF 1.23.4 in the function fz_new_pixmap_from_float_data() of pixmap.c.

A flaw was found in ghostscript. The fix for CVE-2020-16305 in ghostscript was not included in RHSA-2021:1852-06 advisory as it was claimed to be. This issue only affects the ghostscript package as shipped with Red Hat Enterprise Linux 8.

An issue was discovered in the function gdev_prn_open_printer_seekable() in Artifex Ghostscript through 10.02.0 allows remote attackers to crash the application via a dangling pointer.

Artifex Software jbig2dec v0.20 was discovered to contain a SEGV vulnerability via jbig2_error at /jbig2dec/jbig2.c.

In Artifex Ghostscript through 10.01.2, gdevijs.c in GhostPDL can lead to remote code execution via crafted PostScript documents because they can switch to the IJS device, or change the IjsServer parameter, after SAFER has been activated. NOTE: it is a documented risk that the IJS server can be specified on a gs command line (the IJS device inherently must execute a command to start the IJS server).

An integer overflow flaw was found in pcl/pl/plfont.c:418 in pl_glyph_name in ghostscript. This issue may allow a local attacker to cause a denial of service via transforming a crafted PCL file to PDF format.

A buffer overflow flaw was found in base/gdevdevn.c:1973 in devn_pcx_write_rle() in ghostscript. This issue may allow a local attacker to cause a denial of service via outputting a crafted PDF file for a DEVN device with gs.

MuPDF v1.21.1 was discovered to contain an infinite recursion in the component pdf_mark_list_push. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted PDF file.

In Artifex MuJS through 1.2.0, jsP_dumpsyntax in jsdump.c has a NULL pointer dereference, as demonstrated by mujs-pp.

compile in regexp.c in Artifex MuJS through 1.2.0 results in stack consumption because of unlimited recursion, a different issue than CVE-2019-11413.

A NULL pointer dereference vulnerability was found in Ghostscript, which occurs when it tries to render a large number of bits in memory. When allocating a buffer device, it relies on an init_device_procs defined for the device that uses it as a prototype that depends upon the number of bits per pixel. For bpp > 64, mem_x_device is used and does not have an init_device_procs defined. This flaw allows an attacker to parse a large number of bits (more than 64 bits per pixel), which triggers a NULL ...

A vulnerability classified as problematic was found in GhostPCL 9.55.0. This vulnerability affects the function chunk_free_object of the file gsmchunk.c. The manipulation with a malicious file leads to a memory corruption. The attack can be initiated remotely but requires user interaction. The exploit has been disclosed to the public as a POC and may be used. It is recommended to apply the patches to fix this issue.

A Floating point exception (division-by-zero) flaw was found in Mupdf for zero width pages in muraster.c. It is fixed in Mupdf-1.20.0-rc1 upstream.

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).

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 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 interpreter. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

A flaw was found in mupdf 1.18.0. Double free of object during linearization may lead to memory corruption and other potential consequences.

MuPDF through 1.18.1 has an out-of-bounds write because the cached color converter does not properly consider the maximum key size of a hash table. This can, for example, be seen with crafted "mutool draw" input.
