2018-01-27漏洞描述
ClamAV AntiVirus软件版本0.99.2及更早版本包含一个漏洞，该漏洞可能允许未经身份验证的远程攻击者导致拒绝服务(DoS)情况或可能在受影响的设备上执行任意代码。该漏洞是由于处理发送到受影响设备的 Portable Document Format(.pdf)文件时输入验证检查机制不正确所致。未经身份验证的远程攻击者可以通过向受影响的设备发送精心设计的.pdf文件来利用此漏洞。当ClamAV扫描恶意文件时，此操作可能导致handle_pdfname(在pdf.c中)缓冲区溢出，从而允许攻击者导致DoS条件或可能执行任意代码。解决建议
目前厂商已发布升级补丁以修复漏洞，补丁获取链接：http://blog.clamav.net/2018/01/clamav-0993-has-been-released.html受影响软件情况
