Source: NVD (National Vulnerability Database)
Vulnerability Description
A heap-based out-of-bounds read vulnerability in RWObj_Reader::read in the OBJ file parser in Open CASCADE Technology (OCCT) V8_0_0_rc5 allows user-assisted attackers to cause a denial of service or obtain sensitive information by persuading a victim to open a crafted OBJ file. The issue occurs because Standard_ReadLineBuffer::ReadLine() can return a 1-byte buffer for a minimal OBJ line, and RWObj_Reader::read() calls pushIndices(aLine + 2) without validating the buffer length.

Open Cascade OCCT 缓冲区错误漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Open Cascade OCCT是法国Open Cascade公司的一个三维建模与几何计算内核。 Open Cascade OCCT V8_0_0_rc5版本存在缓冲区错误漏洞，该漏洞源于OBJ文件解析器中RWObj_Reader::read函数存在基于堆的越界读取问题，因为Standard_ReadLineBuffer::ReadLine可能返回1字节缓冲区，且RWObj_Reader::read在未验证缓冲区长度的情况下调用pushIndices，可能导致拒绝服务或敏感信息泄露。
