Integer Overflow Buffer Overflow

Description

A vulnerability was identified in NASA cFS up to 7.0.0 on 32-bit. Affected is the function CFE_TBL_ValidateCodecLoadSize of the file cfe/modules/tbl/fsw/src/cfe_tbl_passthru_codec.c. The manipulation leads to integer overflow. The complexity of an attack is rather high. The exploitability is told to be difficult. A fix is planned for the upcoming version milestone of the project.

Analysis

Integer overflow in NASA cFS CFE_TBL_ValidateCodecLoadSize function (cfe_tbl_passthru_codec.c) on 32-bit systems allows authenticated local attackers with low privileges to cause limited integrity and availability impact, though exploitation requires high attack complexity and no public exploit code has been identified; a fix is planned for an upcoming release milestone.
