Name of the Vulnerable Software and Affected Versions libcrypt++ version 5.6.2

Description The issue concerns the InvertibleRWFunction::CalculateInverse function in libcrypt++, which fails to properly blind private key operations for the Rabin-Williams digital signature algorithm. This oversight allows remote attackers to obtain private keys via a timing attack.

Recommendations For libcrypt++ version 5.6.2, consider disabling the InvertibleRWFunction::CalculateInverse function until a patch is available to prevent potential exploitation. Restrict access to private key operations to minimize the risk of obtaining private keys through a timing attack. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
