-Subject: [PATCH] thumbnail: Check shm size before writing to it
-
-The SHM is created by the application, which might've done a different size
-calculation. Verify that the data fits instead of writing past the end and
-crashing.
-
-CCBUG: 430862
-
-
-(cherry picked from commit 112b67ae7895bdc4f32d851c09a4d6baecbb6666)
