The xps_select_font_encoding function in xps/xpsfont.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document, related to the xps_encode_font_char_imp function.

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.

  - ghostscript: /invalidaccess bypass after failed restore (699654) (CVE-2018-16509)

  - ghostscript: Improperly implemented security check in zsetdevice function in psi/zdevice.c     (CVE-2018-19409)

  - The getenv and filenameforall functions in Ghostscript 9.10 ignore the -dSAFER argument, which allows     remote attackers to read data via a crafted postscript file. (CVE-2013-5653)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 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.

  - ghostscript: Improperly implemented security check in zsetdevice function in psi/zdevice.c     (CVE-2018-19409)

  - Integer overflow in the gs_heap_alloc_bytes function in base/gsmalloc.c in Ghostscript 9.15 and earlier     allows remote attackers to cause a denial of service (crash) via a crafted Postscript (ps) file, as     demonstrated by using the ps2pdf command, which triggers an out-of-bounds read or write. (CVE-2015-3228)

  - The pdf14_open function in base/gdevp14.c in Artifex Software, Inc. Ghostscript 9.20 allows remote     attackers to cause a denial of service (use-after-free and application crash) via a crafted file that is     mishandled in the color management module. (CVE-2016-10217)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 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.

  - ghostscript: use-after-free in xps_finish_image_path() in devices/vector/gdevxps.c could result in a     privilege escalation (CVE-2020-16303)

  - Integer overflow in the gs_heap_alloc_bytes function in base/gsmalloc.c in Ghostscript 9.15 and earlier     allows remote attackers to cause a denial of service (crash) via a crafted Postscript (ps) file, as     demonstrated by using the ps2pdf command, which triggers an out-of-bounds read or write. (CVE-2015-3228)

  - The pdf14_open function in base/gdevp14.c in Artifex Software, Inc. Ghostscript 9.20 allows remote     attackers to cause a denial of service (use-after-free and application crash) via a crafted file that is     mishandled in the color management module. (CVE-2016-10217)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote host is affected by the vulnerability described in GLSA-201811-12 (GPL Ghostscript: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in GPL Ghostscript. Please       review the CVE identifiers referenced below for additional information.
  Impact :

    A context-dependent attacker could entice a user to open a specially       crafted PostScript file or PDF document using GPL Ghostscript possibly       resulting in the execution of arbitrary code with the privileges of the       process, a Denial of Service condition, or other unspecified impacts,   Workaround :

    There is no known workaround at this time.
