The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the \"name\" (for example, \"CERTIFICATE\"), any header data, and the payload data. If the function succeeds, then the \"name_out,\" \"header,\" and \"data\" arguments are populated with pointers to buffers containing the relevant decoded data. The caller is responsible for freeing those buffers. Constructing a PEM file that results in 0 bytes of payload data is possible. In this case, PEM_read_bio_ex() will return a failure code but will populate the header argument with a pointer to a freed buffer. A double-free will occur if the caller also frees this buffer. This will most likely lead to a crash. This could be exploited by an attacker who can supply malicious PEM files for parsing to achieve a denial of service attack.",

          "text": "A use-after-free vulnerability was found in OpenSSL\u0027s BIO_new_NDEF function. The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally by OpenSSL to support the SMIME, CMS, and PKCS7 streaming capabilities, but it may also be called directly by end-user applications. The function receives a BIO from the caller, prepends a new BIO_f_asn1 filter BIO onto the front of it to form a BIO chain, and then returns the new head of the BIO chain to the caller. Under certain conditions. For example, if a CMS recipient public key is invalid, the new filter BIO is freed, and the function returns a NULL result indicating a failure. However, in this case, the BIO chain is not properly cleaned up, and the BIO passed by the caller still retains internal pointers to the previously freed filter BIO. If the caller then calls BIO_pop() on the BIO, a use-after-free will occur, possibly resulting in a crash.",

The vulnerability affects all RSA padding modes: PKCS#1 v1.5,\nRSA-OEAP and RSASVE.\n\nFor example, in a TLS connection, RSA is commonly used by a client to send an\nencrypted pre-master secret to the server. An attacker that had observed a\ngenuine connection between a client and a server could use this flaw to send\ntrial messages to the server and record the time taken to process them.
