Artifex Ghostscript before 9.53.0 has an out-of-bounds write and use-after-free in devices/vector/gdevtxtw.c (for txtwrite) because a single character code in a PDF document can map to more than one Unicode code point (e.g., for a ligature).

According to the versions of the ghostscript packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Artifex Ghostscript before 9.53.0 has an out-of-bounds write and use-after-free in     devices/vector/gdevtxtw.c (for txtwrite) because a single character code in a PDF document can map to more     than one Unicode code point (e.g., for a ligature). (CVE-2020-36773)

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2024:0920-1 advisory.

  - Artifex Ghostscript before 9.53.0 has an out-of-bounds write and use-after-free in     devices/vector/gdevtxtw.c (for txtwrite) because a single character code in a PDF document can map to more     than one Unicode code point (e.g., for a ligature). (CVE-2020-36773)

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

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2024:0921-1 advisory.

  - Artifex Ghostscript before 9.53.0 has an out-of-bounds write and use-after-free in     devices/vector/gdevtxtw.c (for txtwrite) because a single character code in a PDF document can map to more     than one Unicode code point (e.g., for a ligature). (CVE-2020-36773)

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

The version of ghostscript installed on the remote host is prior to 9.25-5. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2469 advisory.
