CVE编号
CVE-2018-0202利用情况
POC 已公开补丁情况
官方补丁披露时间
2018-03-27漏洞描述
在0.99.4之前，ClamAV中的clamscan包含一个漏洞，该漏洞允许未经身份验证的远程攻击者在受影响的设备上造成拒绝服务(DoS)条件。此漏洞是由于在处理发送到受影响设备的Portable Document Format (.pdf) files时，输入验证检查机制不正确造成的。未经身份验证的远程攻击者可以通过向受影响设备发送精心编制的.pdf文件来攻击此漏洞。当ClamAV扫描恶意文件时，此操作可能导致超出范围的读取，从而允许攻击者造成DoS条件。这涉及libclav/pdfng.c中的pdf_PARASE_数组和pdf_PARY_String。Ciscobug ID：cscvh 91380，cscvh 91400。 解决建议
