Information Exposure Affecting open-quantum-safe/liboqs package, versions [,0.14.0-rc1)
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Upgrade open-quantum-safe/liboqs to version 0.14.0-rc1 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure via secret-dependent branching in the HQC reference implementation when compiled with Clang at optimization levels above -O0. An attacker can recover the entire secret key by exploiting observable differences in execution paths. This is only exploitable if the code is compiled with Clang using optimization levels -O1 or higher.
