Integer Overflow or Wraparound
An integer overflow issue has been reported in the general_composite_rect() function in pixman prior to version 0.32.8. An attacker could exploit this issue to cause an application using pixman to crash or, potentially, execute arbitrary code.
CWE-190 - Integer Overflow or Wraparound
The software performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control.
