The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2023:0141 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-28879:
    In Artifex Ghostscript through 10.01.0, there is a buffer overflow leading to potential corruption of data     internal to the PostScript interpreter, in base/sbcp.c. This affects BCPEncode, BCPDecode, TBCPEncode, and     TBCPDecode. If the write buffer is filled to one byte less than full, and one then tries to write an     escaped character, two bytes are written.

    CVE-2023-38559:
    A buffer overflow flaw was found in base/gdevdevn.c:1973 in devn_pcx_write_rle() in ghostscript. This     issue may allow a local attacker to cause a denial of service via outputting a crafted PDF file for a DEVN     device with gs.

    CVE-2023-4042:
    A flaw was found in ghostscript. The fix for CVE-2020-16305 in ghostscript was not included in     RHSA-2021:1852-06 advisory as it was claimed to be. This issue only affects the ghostscript package as     shipped with Red Hat Enterprise Linux 8.

    CVE-2023-43115:
    In Artifex Ghostscript through 10.01.2, gdevijs.c in GhostPDL can lead to remote code execution via     crafted PostScript documents because they can switch to the IJS device, or change the IjsServer parameter,     after SAFER has been activated. NOTE: it is a documented risk that the IJS server can be specified on a gs     command line (the IJS device inherently must execute a command to start the IJS server).

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in ghostscript. The fix for CVE-2020-16305 in ghostscript was not included in     RHSA-2021:1852-06 advisory as it was claimed to be. This issue only affects the ghostscript package as     shipped with Red Hat Enterprise Linux 8. (CVE-2023-4042)

Note that Nessus relies on the presence of the package as reported by the vendor.
