{"schemaVersion":3,"id":"CVE-2017-12375","aliases":["ALPINE-CVE-2017-12375","UBUNTU-CVE-2017-12375","DEBIAN-CVE-2017-12375"],"status":"published","duplicateOf":null,"title":null,"description":"The ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of input validation checking mechanisms during certain mail parsing functions (the rfc2047 function in mbox.c). An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. This action could cause a buffer overflow condition when ClamAV scans the malicious email, allowing the attacker to potentially cause a DoS condition on an affected device.","dates":{"published":"2018-01-26T20:00:00.000Z","modified":"2024-12-02T21:26:40.248Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.8,"severity":"high","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":7.8,"severity":"high","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","exploitability":null,"impact":null,"computed":false},{"version":"3.0","versionLabel":"v3.0","source":"OSV
