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.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

An update for ghostscript is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link (s) in the References section.

The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed.

The following packages have been upgraded to a later upstream version:
ghostscript (9.25). (BZ#1636115)

Security Fix(es) :

* ghostscript: status command permitted with -dSAFER in psi/zfile.c allowing attackers to identify the size and existence of files (CVE-2018-11645)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Several vulnerabilities were discovered in Ghostscript, the GPL PostScript/PDF interpreter, which may result in denial of service, disclosure of existence and size of arbitrary files, or the execution of arbitrary code if a malformed Postscript file is processed (despite the dSAFER sandbox being enabled).

This update rebases ghostscript for stretch to the upstream version 9.25 which includes additional non-security related changes.

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)

An issue was discovered in Artifex Ghostscript before 9.24. A type confusion in 'ztype' could be used by remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact.(CVE-2018-16511)

An issue was discovered in Artifex Ghostscript before 9.24. The .setdistillerkeys PostScript command is accepted even though it is not intended for use during document processing (e.g., after the startup phase). This leads to memory corruption, allowing remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact.(CVE-2018-16585)

It was discovered that the ghostscript PDF14 compositor did not properly handle the copying of a 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-2018-16540)

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 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)

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 ghostscript did not properly handle certain stack overflow error conditions. 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-2018-16542)

Ghostscript did not honor the -dSAFER option when executing the 'status' instruction, which can be used to retrieve information such as a file's existence and size. A specially crafted postscript document could use this flow to gain information on the targeted system's filesystem content.(CVE-2018-11645)

It was discovered that the ghostscript did not properly validate the operands passed to the setcolor function. 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-2018-16513)

It was discovered that the type of the LockDistillerParams parameter is not properly verified. 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-2018-15910)

It was discovered that the ghostscript /invalidaccess checks fail under certain conditions. An attacker could possibly exploit this to bypass the -dSAFER protection and, for example, execute arbitrary shell commands via a specially crafted PostScript document.(CVE-2018-16509)

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 .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)

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3768-1 advisory.

    Tavis Ormandy discovered multiple security issues in Ghostscript. 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Tavis Ormandy discovered multiple vulnerabilities in Ghostscript, an interpreter for the PostScript language, which could result in denial of service, the creation of files or the execution of arbitrary code if a malformed Postscript file is processed (despite the dSAFER sandbox being enabled).

For Debian 8 'Jessie', these problems have been fixed in version 9.06~dfsg-2+deb8u8.

We recommend that you upgrade your ghostscript packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
