Description
APR-util versions 1.6.3 (and earlier) function apr_password_validate() was not constant-time with regards to hashes or passwords comparisons, potentially leaking their content via a side channel timing attack particularly on platforms without crypt() such as Windows, BeOS, NetWare, or Android.
Users are recommended to upgrade to version 1.6.4, which fixes this issue.
Affected configurations
• apache apr-util (>= 1.2.0 < 1.6.4)
