Vulnerability Title
Zserio: Integer Overflow in BitStreamReader on 32-bit platforms
Vulnerability Description
Zserio is a framework for serializing structured data with a compact and efficient way with low overhead. Prior to 2.18.1, in BitStreamReader.h readBytes() / readString(), the setBitPosition() bounds check receives the overflowed value and is completely bypassed. The code then reads len bytes (512 MB) from a buffer that is only a few bytes long, causing a segmentation fault. This vulnerability is fixed in 2.18.1.

Vulnerability Title
zserio 输入验证错误漏洞
Vulnerability Description
zserio是Navigation Data Standard e.V.开源的一个高效序列化结构化数据的框架。 zserio 2.18.1之前版本存在输入验证错误漏洞,该漏洞源于BitStreamReader.h中readBytes()/readString()函数的setBitPosition()边界检查被溢出值绕过,导致从仅几字节的缓冲区读取512 MB数据,引发分段错误。
