Threat & Defense Details

Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-30 Concealment and Misdirection
addresses: CWE-208

Timing randomization or delays can mask true operation timing and mislead timing-based attacks.

SC-31 Covert Channel Analysis
addresses: CWE-208

Observable timing discrepancies are a primary mechanism for constructing covert timing channels; analysis identifies and bounds them, limiting exploitation.

NVD Description

Crypt::SaltedHash versions through 0.09 for Perl is susceptible to timing attacks. These versions use Perl's built-in eq comparison. Discrepencies in timing could be used to guess the underlying hash.
