7 | Subject: [PATCH] Prevent over long nonces in ChaCha20-Poly1305 | ||
8 | |||
9 | ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for | ||
10 | every encryption operation. RFC 7539 specifies that the nonce value (IV) | ||
11 | should be 96 bits (12 bytes). OpenSSL allows a variable nonce length and | ||
12 | front pads the nonce with 0 bytes if it is less than 12 bytes. However it | ||
13 | also incorrectly allows a nonce to be set of up to 16 bytes. In this case | ||
14 | only the last 12 bytes are significant and any additional leading bytes are | ||
15 | ignored. | ||
16 | |||
17 | It is a requirement of using this cipher that nonce values are unique. | ||
18 | Messages encrypted using a reused nonce value are susceptible to serious | ||
19 | confidentiality and integrity attacks. If an application changes the | ||
20 | default nonce length to be longer than 12 bytes and then makes a change to | ||
21 | the leading bytes of the nonce expecting the new value to be a new unique | ||
22 | nonce then such an application could inadvertently encrypt messages with a | ||
23 | reused nonce. | ||
24 | |||
25 | Additionally the ignored bytes in a long nonce are not covered by the | ||
26 | integrity guarantee of this cipher. Any application that relies on the | ||
27 | integrity of these ignored leading bytes of a long nonce may be further | ||
28 | affected. | ||
29 | |||
30 | Any OpenSSL internal use of this cipher, including in SSL/TLS, is safe | ||
31 | because no such use sets such a long nonce value. However user | ||
32 | applications that use this cipher directly and set a non-default nonce | ||
33 | length to be longer than 12 bytes may be vulnerable. | ||
