Summary: Long expressions in shaders crash Mesa
Severity: normal
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: Other
Status: NEW
Version: 9.1
Component: Mesa core
Product: Mesa
A long expression in a GLSL shader will crash Mesa, the crash occurs after
parsing in generating the HIR from the AST.
Attached is a vertex shader with such a long expression (10,000 add terms).
The bug issue is that although such a shader is not to be found in "real"
applications, a malicious website can use WebGL to crash Mesa which would
likely crash the browser.
