Name of the Vulnerable Software and Affected Versions
ThreadX (affected versions not specified)
Description
Two issues exist in the loadable-module loader. These are triggered when a device loads an attacker-controlled module object using the
txm module manager memory load or txm module manager in place load APIs. Because these APIs only accept a base pointer and no image length, all size and offset fields in the TXM MODULE PREAMBLE are trusted. This leads to a heap out-of-bounds read, where the code size variable is trusted as the source-image length during the code-copy loop. Additionally, there is a control-flow-integrity gap where module entry, start, callback, and stop pointers are calculated as code start + preamble offset with only a non-zero check, and the preamble checksum is not verified.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
Insufficient Verification of Data Authenticity
Out of bounds Read
