Title: Objective Systems ASN1C堆缓冲区溢出漏洞

Description:

ASN.1是一套标准，是描述数据的表示、编码、传输、解码记法。ASN1C可按ASN.1语法生成高级语言代码。

ASN1C for C/C++ < 7.0.2版本，asn1rt_a.lib/rtxMemHeapAlloc函数存在整数溢出漏洞。攻击者利用漏洞通过构造的ASN.1数据，可执行任意代码或造成拒绝服务。

Severity: 高

Summary

Integer overflow in the rtxMemHeapAlloc function in asn1rt_a.lib in Objective Systems ASN1C for C/C++ before 7.0.2 allows context-dependent attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow), on a system running an application compiled by ASN1C, via crafted ASN.1 data.
