Description

A 32-bit unsigned integer overflow in the XWD (X Windows) encoder can cause an undersized heap buffer allocation. When writing a extremely large image an out of bounds heap write can occur. ``` ================================================================= ==741961==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x5020000083dc at pc 0x56553b4c4245 bp 0x7ffd9d20fef0 sp 0x7ffd9d20fee0 WRITE of size 1 at 0x5020000083dc thread T0 ```
