{"id":"ALPINE-CVE-2025-20128","details":"A vulnerability in the Object Linking and Embedding 2 (OLE2) decryption routine of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.\r\n\r\nThis vulnerability is due to an integer underflow in a bounds check that allows for a heap buffer overflow read. An attacker could exploit this vulnerability by submitting a crafted file containing OLE2 content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to terminate the ClamAV scanning process, resulting in a DoS condition on the affected software.\r\nFor a description of this vulnerability, see the .\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.","modified":"2026-11-03T06:33:00.338881118Z","published":"2025-01-22T17:15:12.583Z","upstream":["CVE-2025-20128"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2025-20128"}],"affected":[{"package":{"name":"clamav","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/clamav?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.0"},{"fixed":"1.4.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-20128.json"}},{"package":{"name":"clamav","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/clamav?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.0"},{"fixed":"1.4.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-20128.json"}},{"package":{"name":"clamav","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/clamav?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.0"},{"fixed":"1.4.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-20128.json"}},{"package":{"name":"clamav","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/clamav?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.0"},{"fixed":"1.4.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-20128.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
