The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6835-1 advisory.

    It was discovered that Ghostscript did not properly restrict eexec seeds to those specified by the Type 1     Font Format standard when SAFER mode is used. An attacker could use this issue to bypass SAFER     restrictions and cause unspecified impact. (CVE-2023-52722) This issue only affected Ubuntu 20.04 LTS,     Ubuntu 22.04 LTS, and Ubuntu 23.10.

    Thomas Rinsma discovered that Ghostscript did not prevent changes to uniprint device argument strings     after SAFER is activated, resulting in a format-string vulnerability. An attacker could possibly use this     to execute arbitrary code. (CVE-2024-29510)

    Zdenek Hutyra discovered that Ghostscript did not properly perform path reduction when validating paths.
    An attacker could use this to access file locations outside of those allowed by SAFER policy and possibly     execute arbitrary code. (CVE-2024-33869)

    Zdenek Hutyra discovered that Ghostscript did not properly check arguments when reducing paths. An     attacker could use this to access file locations outside of those allowed by SAFER policy.
    (CVE-2024-33870)

    Zdenek Hutyra discovered that the Driver parameter for Ghostscript's opvp/oprp device allowed     specifying the name of an arbitrary dynamic library to load. An attacker could use this to execute     arbitrary code. (CVE-2024-33871)

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.
