N/A

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 or potentially execute arbitrary code on an affected device. The vulnerability is due to improper input validation checking mechanisms in mew packet files sent to an affected device. A successful exploit could cause a heap-based buffer over-read condition in mew.c when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code on the affected device.

ClamAV AntiVirus software 缓冲区错误漏洞

ClamAV AntiVirus software是ClamAV团队开发的一套免费且开源的杀毒软件。该软件用于检测木马、病毒、恶意软件和其他恶意威胁。 ClamAV AntiVirus software 0.99.2及之前的版本中的mew.c文件存在堆溢出漏洞，该漏洞源于程序没有对mew数据文件执行正确的输入验证检测。远程攻击者可借助恶意的文件利用该漏洞造成拒绝服务或可能执行任意代码（基于堆的缓冲区越边界读取）。
