What is CVE-2017-12375?
CVE-2017-12375 is a high-severity memory corruption vulnerability in Clamav Clamav, published on 26 Jan 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
