Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the OPENSSL_uni2utf8() function. If a user can be convinced to process a malicious PKCS#12 file, the attacker can supply a BMPString (UTF-16BE) friendly name containing a non-ASCII BMP code point, which triggers unintended behavior and denial of service.
