"The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the
openSUSE-SU-2023:0108-1 advisory.

  - OFFIS DCMTK's (All versions prior to 3.6.7) service class provider (SCP) is vulnerable to path traversal,
    allowing an attacker to write DICOM files into arbitrary directories under controlled names. This could
    allow remote code execution. (CVE-2022-2119)

  - OFFIS DCMTK's (All versions prior to 3.6.7) service class user (SCU) is vulnerable to relative path
    traversal, allowing an attacker to write DICOM files into arbitrary directories under controlled names.
    This could allow remote code execution. (CVE-2022-2120)

  - OFFIS DCMTK's (All versions prior to 3.6.7) has a NULL pointer dereference vulnerability while processing
    DICOM files, which may result in a denial-of-service condition. (CVE-2022-2121)

  - DCMTK v3.6.7 was discovered to contain a memory leak via the T_ASC_Association object. (CVE-2022-43272)

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