There are two copy-paste errors in handling CTR mode. When dealing with a 2 or 3 block tail, the code branches to the CBC decryption exit path, rather than to the CTR exit path. This can lead to data corruption: in the Linux kernel we have a copy of this file, and the bug leads to corruption of the IV, which leads to data corruption when we call the encryption function again later to encrypt subsequent blocks.

The previous commit fixed an underflow that may occur in ecp_nistp521.c. This commit adds a test for that condition. It is heavily based on an original test harness by Billy Brumley. Reviewed-by:

The function felem_diff_128_64 in ecp_nistp521.c substracts the number |in| from |out| mod p. In order to avoid underflow it first adds 32p mod p (which is equivalent to 0 mod p) to |out|. The comments and variable naming suggest that the original author intended to add 64p mod p. In fact it has been shown that with certain unusual co-ordinates it is possible to cause an underflow in this function when only adding 32p mod p while performing a point double operation. By changing this to 64p mod p the underflow is avoided. It turns out to be quite difficult to construct points that satisfy the underflow criteria although this has been done and the underflow demonstrated. However none of these points are actually on the curve. Finding points that satisfy the underflow criteria and are also *on* the curve is considered significantly more difficult. For this reason we do not believe that this issue is currently practically exploitable and therefore no CVE has been assigned. This only impacts builds using the enable-ec_nistp_64_gcc_128 Configure option. With thanks to Bo-Yin Yang, Billy Brumley and Dr Liu for their significant help in investigating this issue.

ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value (IV) should be 96 bits (12 bytes). OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also incorrectly allows a nonce to be set of up to 16 bytes. In this case only the last 12 bytes are significant and any additional leading bytes are ignored. It is a requirement of using this cipher that nonce values are unique. Messages encrypted using a reused nonce value are susceptible to serious confidentiality and integrity attacks. If an application changes the default nonce length to be longer than 12 bytes and then makes a change to the leading bytes of the nonce expecting the new value to be a new unique nonce then such an application could inadvertently encrypt messages with a reused nonce. Additionally the ignored bytes in a long nonce are not covered by the integrity guarantee of this cipher. Any application that relies on the integrity of these ignored leading bytes of a long nonce may be further affected. Any OpenSSL internal use of this cipher, including in SSL/TLS, is safe because no such use sets such a long nonce value. However user applications that use this cipher directly and set a non-default nonce length to be longer than 12 bytes may be vulnerable. CVE-2019-1543 Fixes #8345 Reviewed-by:

This makes `--strict-warnings` into a compiler pseudo-option, i.e. it gets treated the same way as any other compiler option given on the configuration command line, but is retroactively replaced by actual compiler warning options, depending on what compiler is used. This makes it easier to see in what order options are given to the compiler from the configuration command line, i.e. this: ./config -Wall --strict-warnings would give the compiler flags in the same order as they're given, i.e.: -Wall -Werror -Wno-whatever ... instead of what we got previously: -Werror -Wno-whatever ... -Wall (cherry picked from commit fcee53948b7f9a5951d42f4ee321e706ea6b4b84) Reviewed-by:
