The version of ghostscript installed on the remote host is prior to 9.54.0-9. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2820 advisory.

    Fix confusion between bytes and shorts. Data is being copied from a string in multiple of shorts, rather     than multiple of bytes, leading to both a read (probably benign, given the memory manager) and write     buffer overflow.

    Info: https://bugs.ghostscript.com/show_bug.cgi?id=708131Patch: https://cgit.ghostscript.com/cgi-     bin/cgit.cgi/ghostpdl.git/commit/?id=de900010a6f2310d1fd54e99eeba466693da0e13 (ghostpdl-10.05.0)     (CVE-2025-27835)

    Potential print buffer overflow. Fixed in ghostpdl-10.05.0 by implementing stricter buffer length     validation.

    Patch to error check UTF-8 conversions. Fixed in ghostpdl-10.05.0 by adding a check on the value returned     by the gp_utf8_to_uint16 function.
