Uses insecure CSPRNG (openssl_random_pseudo_bytes())

It's not fork safe In most versions of PHP, it lies about being secure And today I learned that OpenSSL, by default i.e. unchangable from PHP land uses MD5 as a CSPRNG thanks @atoponce I'm stuck between several possible avenues: Release a new version v1.3.0 or most likely v2.0.0 that doesn't rely...

Vulnerability in OpenSSL - Use After Free following d2i_ECPrivatekey error

Use After Free following d2iECPrivatekey error. A malformed EC private key file consumed via the d2iECPrivateKey function could cause a use after free condition. This, in turn, could cause a double free in several private key parsing functions such as d2iPrivateKey or EVPPKCS82PKEY and could lead...
