PHP openssl_x509_parse() Memory Corruption Vulnerability

The PHP function opensslx509parse uses a helper function called asn1timetotimet to convert timestamps from ASN1 string format into integer timestamp values. The parser within this helper function is not binary safe and can therefore be tricked to write up to five NUL bytes outside of an allocated...
