Vulnerability from cnvd

Title: Wireshark 'epan/wslua/wslua_file.c'拒绝服务漏洞

Description:

Wireshark是一个网络封包分析软件。网络封包分析软件的功能是撷取网络封包，并尽可能显示出最为详细的网络封包资料。Wireshark使用WinPCAP作为接口，直接与网卡进行数据报文交换。

Wireshark 2.2.11及之前的版本中的存在拒绝服务漏洞，该漏洞产生的原因是Wireshark中的epan/wslua/wslua_file.c中的File_read_line函数未能正确去除'n'字符。远程攻击者可通过特制数据包（触发处理空行的尝试）利用该漏洞导致拒绝服务（缓冲区溢出和应用程序崩溃）。

Severity: 中

Severity ?

CWE

Summary

The File_read_line function in epan/wslua/wslua_file.c in Wireshark through 2.2.11 does not properly strip '\n' characters, which allows remote attackers to cause a denial of service (buffer underflow and application crash) via a crafted packet that triggers the attempted processing of an empty line.
