Vulnerability Description
The auth_gssapi_unwrap_data function in lib/rpc/auth_gssapi_misc.c in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 does not properly handle partial XDR deserialization, which allows remote authenticated users to cause a denial of service (use-after-free and double free, and daemon crash) or possibly execute arbitrary code via malformed XDR data, as demonstrated by data sent to kadmind.

MIT Kerberos 5 远程代码执行漏洞
Vulnerability Description
MIT Kerberos 5（又名krb5）是美国麻省理工学院（MIT）开发的一套网络认证协议，它采用客户端/服务器结构，并且客户端和服务器端均可对对方进行身份认证（即双重验证），可防止窃听、防止replay攻击等。 MIT Kerberos 5的lib/rpc/auth_gssapi_misc.c文件中的‘auth_gssapi_unwrap_data’函数存在安全漏洞，该漏洞源于程序没有正确处理局部XDR声明。远程攻击者可借助畸形的XDR数据利用该漏洞造成拒绝服务（释放后重用和双重释放，守护进程崩溃）
