Описание
liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. Multiple secret-dependent branches have been identified in the reference implementation of the HQC key encapsulation mechanism when it is compiled with Clang for optimization levels above -O0 (-O1, -O2, etc). A proof-of-concept local attack exploits this secret-dependent information to recover the entire secret key. This vulnerability is fixed in 0.14.0.
An observable discrepancy was found in the reference implementation of the HQC key encapsulation mechanism when it is compiled with Clang for optimization levels above -O0 onto -O1, -O2, and beyond. A proof-of-concept local attack exploits this secret-dependent information to recover the entire secret key.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
