Amounts are the top reward per severity in the currency each program pays. Green marks the highest per severity. First response is the platform's measured average when it publishes one, else what the policy promises.
What is in scope
9 targets across all 2 programs, each listed once with the programs that cover it. 5 excluded.
-
Reports go through the contact in the project's SECURITY.md, and what is covered is the Ghostscript tree itself, reachable however a downstream caller feeds it. Nothing narrower is carved out
Products and areas
Covered by Sorona
-
The -dSAFER sandbox and every restriction it is supposed to impose, since SAFER is the guarantee every downstream integrator relies on when it feeds Ghostscript an untrusted file
Products and areas
Covered by Sorona
-
The command-line front end and the options, resource paths and initialisation files it accepts, which is what downstream delegate invocations such as ImageMagick's are built on
Products and areas
Covered by Sorona
-
The glue around the bundled jbig2dec, JPEG and lcms decoders, where Ghostscript hands attacker-controlled data across a library boundary
Products and areas
Covered by Sorona
-
The graphics library and the whole of devices/, covering the raster, printer and display back ends that turn interpreted content into output
Products and areas
Covered by Sorona
-
The gs_* font and CMap machinery, where malformed embedded fonts and character mappings are parsed
Products and areas
Covered by Sorona
-
The PDF interpreter under pdf/, rewritten in C for the Ghostscript 10.x series and therefore comparatively fresh, less-exercised code
Products and areas
Covered by Sorona
-
The PostScript interpreter in full: the language implementation, the operator table, and the place where attacker-written program text is executed directly
Products and areas
Covered by Sorona
No target matches. Try part of a host name, such as the company name.
Out of scope 5
Don't test these. A program can exclude a host another program covers; the program you report to decides.
-
MuPDF, which is a separate Artifex product with its own OSS-Fuzz entry and therefore its own separate Tier 2 line
Sorona
-
One-line patches for non-exploitable crashes and resource-exhaustion denial of service, which the Patch Rewards rules say will not generally be rewarded
Sorona
-
Patches outside the one-to-twelve-month age window the programme applies at submission time
Sorona
-
Patches the Artifex maintainers decline, because the money attaches to a patch that is merged and stays merged rather than to one that is proposed
Sorona
-
Submissions beyond the cap of three per person per month

CVE-2010-4820 Medium
Untrusted search path vulnerability in Ghostscript 8.62 allows local users to execute arbitrary PostScript code via a Trojan horse Postscript library file in Encoding/ under the current working directory, a different vulnerability than CVE-2010-2055.

CVE-2012-4405 Medium
Multiple integer underflows in the icmLut_allocate function in International Color Consortium (ICC) Format library (icclib), as used in Ghostscript 9.06 and Argyll Color Management System, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted (1) PostScript or (2) PDF file with embedded images, which triggers a heap-based buffer overflow.

CVE-2009-4270 High
Stack-based buffer overflow in the errprintf function in base/gsmisc.c in ghostscript 8.64 through 8.70 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PDF file, as originally reported for debug logging code in gdevcups.c in the CUPS output driver.

CVE-2009-0196 High
Heap-based buffer overflow in the big2_decode_symbol_dict function (jbig2_symbol_dict.c) in the JBIG2 decoding library (jbig2dec) in Ghostscript 8.64, and probably earlier versions, allows remote attackers to execute arbitrary code via a PDF file with a JBIG2 symbol dictionary segment with a large run length value.
