Por lo tanto, si es muy grande, ocurre un desbordamiento de enteros seguido por un desbordamiento de búfer. • http://www.securityfocus.com/bid/103671 https://source.android.com/security/bulletin/2018-04-01 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •

In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile and Snapdragon Wear IPQ4019, MDM9206, MDM9607, MDM9625, MDM9635M, MSM8909W, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 600, SD 615/16/SD 415, SD 617, SD 650/52, SD 800, SD 808, and SD 810, in widevine_dash_cmd_handler(), rsp buffers are passed off to widevine commands. These rsp buffers have values in them, such as buffer lengths, that need to be validated to ensure that no buffer overflow/over-reads happen. However, rsp buffers are not always in locked memory, meaning a time-of-check, time-of-use issue can occur where we check that the value is valid, but then a race condition occurs where this memory is swapped out with a different, possibly out of range, value.

Estos búfers rsp tienen valores, como las longitudes de búfer, que necesitan ser validados para asegurar que no ocurren desbordamientos/sobrelecturas de búfer. • http://www.securityfocus.com/bid/103671 https://source.android.com/security/bulletin/2018-04-01 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
