When opening a new file, MiniZip doesn't properly validate the filename, comments, or extra fields length against the data type used to store this information. This may allow an attacker to craft a malicious ZIP file that will lead to an overflow on the length field. This value is further used in memory allocations and indexing, which can cause an out-of-bounds write, leading to heap corruption and possible arbitrary code execution."], "name": "CVE-2023-45853", "package_state": [{"cpe": "cpe:/a:redhat:logging:5", "fix_state": "Not affected", "package_name": "openshift-logging/kibana6-rhel8", "product_name": "Logging Subsystem for Red Hat OpenShift"}, {"cpe": "cpe:/a:redhat:openjdk:11", "fix_state": "Will not fix", "package_name": "zlib", "product_name": "Red Hat build of OpenJDK 11"}, {"cpe": "cpe:/a:redhat:openjdk:17", "fix_state": "Affected", "package_name": "zlib", "product_name": "Red Hat build of OpenJDK 17"}, {"cpe": "cpe:/a:redhat:openjdk:1.8", "fix_state": "Will not fix", "package_name": "zlib", "product_name": "Red Hat build of OpenJDK 1.8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:6", "fix_state": "Out of support scope", "package_name": "zlib", "product_name": "Red Hat Enterprise Linux 6"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Out of support scope", "package_name": "zlib", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Not affected", "package_name": "zlib", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Not affected", "package_name": "zlib", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/a:redhat:openshift_gitops:1", "fix_state": "Not affected", "package_name": "openshift-gitops-1/argocd-rhel8", "product_name": "Red Hat OpenShift GitOps"}, {"cpe": "cpe:/a:redhat:openshift_gitops:1", "fix_state": "Not affected", "package_name": "openshift-gitops-1/argo-rollouts-rhel8", "product_name": "Red Hat OpenShift GitOps"}], "public_date": "2023-10-14T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2023-45853\nhttps://nvd.nist.gov/vuln/detail/CVE-2023-45853"], "statement": "Red Hat Enterprise Linux default configuration doesn't expose zlib through any network services.
