Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the RWStlReader::ReadAscii process when buffers returned by StandardReadLineBuffer::ReadLine are not properly length-validated before being used in strncasecmp or accessed directly. An attacker can cause denial of...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read through the TShape process in the VRML parser when coordIndex values from parsed input are used as direct array indices without validation against the size of the coordinate array during geometry processing. An attack...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the ReadLine process of the VRML parser due to improper bounds checking in the quoted-string escape handler, which accesses memory beyond the end of a fixed-size stack buffer. An attacker can trigger a denial of...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the IGES and STEP file parsing process. An attacker can cause a denial of service or access unintended memory contents by submitting specially crafted IGES or STEP files that trigger out-of-bounds reads or infinit...

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...
