NONE Summary
Ghostscript before 9.21 might allow remote attackers to bypass the SAFER mode protection mechanism and consequently read arbitrary files via the use of the .libfile operator in a crafted postscript document.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Subverting Environment Variable Values The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Exploiting Trust in Client (aka Make the Client Invisible) An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
- Browser Fingerprinting An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
- Session Credential Falsification through Prediction This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

NASL family Huawei Local Security Checks NASL id EULEROS_SA-2020-1499.NASL description According to the versions of the ghostscript package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - The PS Interpreter in Ghostscript 9.18 and 9.20 allows remote attackers to execute arbitrary code via crafted userparams.(CVE-2016-7976) - 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.(CVE-2018-11645) - A flaw was found in the .pdfexectoken and other procedures 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 have access to the file system, or execute arbitrary commands.(CVE-2019-14817) - A flaw was found 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 have access to the file system, or execute arbitrary commands.(CVE-2019-14813) - A flaw was found in the .setuserparams2 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 have access to the file system, or execute arbitrary commands.(CVE-2019-14812) - A flaw was found in the .pdf_hook_DSC_Creator 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 have access to the file system, or execute arbitrary commands.(CVE-2019-14811) - libjbig2dec.a in Artifex jbig2dec 0.13, as used in MuPDF and Ghostscript, has a NULL pointer dereference in the jbig2_huffman_get function in jbig2_huffman.c. For example, the jbig2dec utility will crash (segmentation fault) when parsing an invalid file.(CVE-2017-9216) - Artifex jbig2dec 0.13, as used in Ghostscript, allows out-of-bounds writes because of an integer overflow in the jbig2_build_huffman_table function in jbig2_huffman.c during operations on a crafted JBIG2 file, leading to a denial of service (application crash) or possibly execution of arbitrary code.(CVE-2017-7975) - Artifex jbig2dec 0.13 has a heap-based buffer over-read leading to denial of service (application crash) or disclosure of sensitive information from process memory, because of an integer overflow in the jbig2_decode_symbol_dict function in jbig2_symbol_dict.c in libjbig2dec.a during operation on a crafted .jb2 file.(CVE-2017-7885) - Artifex jbig2dec 0.13 allows out-of-bounds writes and reads because of an integer overflow in the jbig2_image_compose function in jbig2_image.c during operations on a crafted .jb2 file, leading to a denial of service (application crash) or disclosure of sensitive information from process memory.(CVE-2017-7976) - ghostscript before version 9.21 is vulnerable to a heap based buffer overflow that was found in the ghostscript jbig2_decode_gray_scale_image function which is used to decode halftone segments in a JBIG2 image. A document (PostScript or PDF) with an embedded, specially crafted, jbig2 image could trigger a segmentation fault in ghostscript.(CVE-2016-9601) - In Artifex Ghostscript before 9.26, a carefully crafted PDF file can trigger an extremely long running computation when parsing the file.(CVE-2018-19478) - It was found that the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges and access files outside of restricted areas.(CVE-2019-10216) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.
