CVE-2026-42476
Two heap-based out-of-bounds read vulnerabilities affect Open CASCADE Technology (OCCT) V8_0_0_rc5 in the STL ASCII file parser (RWStl_Reader::ReadAscii). In CTL: buffers returned by Standard_ReadLineBuffer::ReadLine() are not properly length-validated before strncasecmp or direct byte access, en...
CVE-2026-42479
An out-of-bounds read vulnerability in VrmlDataIndexedLineSet::TShape in the VRML parser in Open CASCADE Technology OCCT V800rc5 allows attackers to cause a denial of service via a crafted VRML file. The issue occurs because coordIndex values from parsed input are used as direct array indices...
CVE-2026-42477
A heap-based out-of-bounds read vulnerability in RWObjReader::read in the OBJ file parser in Open CASCADE Technology OCCT V800rc5 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...
CVE-2026-42480
A stack-based out-of-bounds read vulnerability in VrmlDataScene::ReadLine in the VRML parser in Open CASCADE Technology OCCT V800rc5 allows attackers to cause a denial of service via a crafted VRML file. The issue occurs because the quoted-string escape handler uses ptr++anOffset without proper...
CVE-2026-42476
