Synopsis

The version of ghostscript installed on the remote host is prior to 9.25-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2308 advisory.- A buffer overflow vulnerability in epsc_print_page() in devices/gdevepsc.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51. (CVE-2020-16294)
- A divide by zero issue discovered in eps_print_page in gdevepsn.c in Artifex Software GhostScript 9.50 allows remote attackers to cause a denial of service via opening of crafted PDF file. (CVE-2020-21710)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
