| Doc Text: |
A flaw was found in Crypt::CBC. Affected versions of Perl may use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. This issue affects operating systems where "/dev/urandom'" is unavailable. In that case, Crypt::CBC will fall back to using the insecure rand() function.

Raised upstream: https://github.com/lstein/Lib-Crypt-CBC/issues/9 Is this ever likely to be an issue on Linux, where /dev/urandom should always be available? In containers perhaps? |
