NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-3773-1.NASL description It was discovered that Ghostscript contained multiple security issues. If a user or automated system were tricked into processing a specially crafted file, a remote attacker could possibly use these issues to access arbitrary files, execute arbitrary code, or cause a denial of service. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 117867 published 2018-10-02 reporter Ubuntu Security Notice (C) 2018-2019 Canonical, Inc. / NASL script (C) 2018-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/117867 title Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : ghostscript vulnerabilities (USN-3773-1) NASL family SuSE Local Security Checks NASL id OPENSUSE-2019-759.NASL description This update for ghostscript to version 9.25 fixes the following issues : These security issues were fixed : - CVE-2018-17183: Remote attackers were be able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code (bsc#1109105) - CVE-2018-15909: Prevent type confusion using the .shfill operator that could have been used by attackers able to supply crafted PostScript files to crash the interpreter or potentially execute code (bsc#1106172). - CVE-2018-15908: Prevent attackers that are able to supply malicious PostScript files to bypass .tempfile restrictions and write files (bsc#1106171). - CVE-2018-15910: Prevent a type confusion in the LockDistillerParams parameter that could have been used to crash the interpreter or execute code (bsc#1106173). - CVE-2018-15911: Prevent use uninitialized memory access in the aesdecode operator that could have been used to crash the interpreter or potentially execute code (bsc#1106195). - CVE-2018-16513: Prevent a type confusion in the setcolor function that could have been used to crash the interpreter or possibly have unspecified other impact (bsc#1107412). - CVE-2018-16509: Incorrect last seen 2020-06-01 modified 2020-06-02 plugin id 123326 published 2019-03-27 reporter This script is Copyright (C) 2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/123326 title openSUSE Security Update : ghostscript (openSUSE-2019-759) NASL family SuSE Local Security Checks NASL id SUSE_SU-2018-2975-1.NASL description This update for ghostscript to version 9.25 fixes the following issues : These security issues were fixed : CVE-2018-17183: Remote attackers were be able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code (bsc#1109105) CVE-2018-15909: Prevent type confusion using the .shfill operator that could have been used by attackers able to supply crafted PostScript files to crash the interpreter or potentially execute code (bsc#1106172).

LockSafetyParams is not checked correctly if another device is used. (CVE-2018-19409) - It was discovered that the ghostscript .tempfile function did not properly handle file permissions. An attacker could possibly exploit this to exploit this to bypass the -dSAFER protection and delete files or disclose their content via a specially crafted PostScript document. (CVE-2018-15908) - An issue was discovered in Artifex Ghostscript before 9.25. Incorrect restoration of privilege checking when running out of stack during exception handling could be used by attackers able to supply crafted PostScript to execute code using the pipe instruction. This is due to an incomplete fix for CVE-2018-16509. (CVE-2018-16802) - It was discovered that the ghostscript device cleanup did not properly handle devices replaced with a null device. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document. (CVE-2018-16541) - It was discovered that ghostscript did not properly verify the key used in aesdecode. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document. (CVE-2018-15911) - It was discovered that the ghostscript did not properly restrict access to files open prior to enabling the -dSAFER mode. An attacker could possibly exploit this to bypass the -dSAFER protection and disclose the content of affected files via a specially crafted PostScript document. (CVE-2018-16539) - Artifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code. (CVE-2018-17183) - Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving errorhandler setup. NOTE: this issue exists because of an incomplete fix for CVE-2018-17183. (CVE-2018-17961) - Artifex Ghostscript allows attackers to bypass a sandbox protection mechanism by leveraging exposure of system operators in the saved execution stack in an error object. (CVE-2018-18073) - Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving the 1Policy operator. (CVE-2018-18284) - It was found that RHSA-2018:2918 did not fully fix CVE-2018-16509. An attacker could possibly exploit another variant of the flaw and bypass the -dSAFER protection to, for example, execute arbitrary shell commands via a specially crafted PostScript document. (CVE-2018-16863) - In Artifex Ghostscript through 9.25, the setpattern operator did not properly validate certain types. A specially crafted PostScript document could exploit this to crash Ghostscript or, possibly, execute arbitrary code in the context of the Ghostscript process. This is a type confusion issue because of failure to check whether the Implementation of a pattern dictionary was a structure type. (CVE-2018-19134) - It was discovered that the ghostscript .shfill operator did not properly validate certain types. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document. (CVE-2018-15909) - It was discovered that the ghostscript .type operator did not properly validate its operands. A specially crafted PostScript document could exploit this to crash ghostscript or, possibly, execute arbitrary code in the context of the ghostscript process.
