Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process.

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

An update of the apache package has been released.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-4874-1 advisory.

    It was discovered that Apache Ant created temporary files with insecure permissions. An attacker could use     this vulnerability to read sensitive information leaked into /tmp, or potentially inject malicious code     into a project that is built with Apache Ant.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The 12.4.0.0 versions of Enterprise Manager Ops Center installed on the remote host are affected by multiple vulnerabilities as referenced in the July 2020 CPU advisory.

  - Vulnerability in the Enterprise Manager Ops Center product of Oracle Enterprise Manager (component:
    Apache Log4j). The supported version that is affected is 12.4.0.0. Easily exploitable vulnerability allows     unauthenticated attacker with network access to compromise Oracle Enterprise Manager Ops Center.
    Successful attacks of this vulnerability can result in takeover of Oracle Enterprise Manager Ops Center.
    (CVE-2017-5645)

  - Vulnerability in the Enterprise Manager Ops Center product of Oracle Enterprise Manager (component:

Easily exploitable     vulnerability allows unauthenticated attacker with network access via HTTP to compromise Enterprise     Manager Ops Center. Successful attacks of this vulnerability can result in unauthorized creation,     deletion or modification access to critical data or all Enterprise Manager Ops Center accessible data as     well as unauthorized access to critical data or complete access to all Enterprise Manager Ops Center     accessible data (CVE-2020-1945).

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4022-1 advisory.

  - As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions of temporary files it created so     that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the     temporary file and created a new one without said protection, effectively nullifying the effort. This     would still allow an attacker to inject modified source files into the build process. (CVE-2020-11979)

    This advisory contains the RPM packages for Red Hat OpenShift Container     Platform 3.11.394. See the following advisory for the container images for this release:

    https://access.redhat.com/errata/RHBA-2021:0638

    Space precludes documenting all of the container images in this advisory. See the following Release Notes     documentation, which will be updated shortly for this release, for details about these changes:

    https://docs.openshift.com/container-platform/3.11/release_notes/ocp_3_11_release_notes.html

    This update fixes the following bugs among others:

    * Previously, the restart-cluster playbook did not evaluate the defined cluster size for ops clusters.
    This was causing come clusters to never complete their restart. This bug fix passes the logging ops     cluster size, allowing restarts of ops clusters to complete successfully. (BZ#1879407)

    * Previously, the `openshift_named_certificates` role checked the contents of the `ca-bundle.crt` file     during cluster installation. This caused the check to fail during initial installation because the `ca-     bundle.crt` file is not yet created in that scenario. This bug fix allows the cluster to skip checking the     `ca-bundle.crt` file if it does not exist, resulting in initial installations succeeding. (BZ#1920567)

    * Previously, if the `openshift_release` attribute was not set in the Ansible inventory file, the nodes of     the cluster would fail during an upgrade. This was caused by the `cluster_facts.yml` file being gathered     before the `openshift_release` attribute was defined by the upgrade playbook. Now the `cluster_facts.yml`     file is gathered after the `openshift_version` role runs and the `openshift_release` attribute is set,     allowing for successful node upgrades. (BZ#1921353)

    All OpenShift Container Platform 3.11 users are advised to upgrade to these updated packages and images.

The remote host is affected by the vulnerability described in GLSA-202007-34 (Apache Ant: Multiple vulnerabilities)

    Apache Ant was found to be using multiple insecure temporary files which       may disclose sensitive information or execute code from an unsafe local       location.
  Impact :

    A local attacker could possibly execute arbitrary code with the       privileges of the process, or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

This update for ant fixes the following issues :

  - CVE-2020-1945: Fixed an inseure temorary file     vulnerability which could have potentially leaked     sensitive information (bsc#1171696).&#9;
