EUVD-2017-12848

If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305; user...

CVE-2017-3732

There is a carry propagating bug in the x8664 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed...

CVE-2017-3731

CVE-2017-3731 describes an out-of-bounds read/crash in SSL/TLS when running on 32-bit hosts using certain ciphers. Public sources in the connected documents show multiple vendors referencing OpenSSL in affected configurations: on OpenSSL 1.1.0, CHACHA20/POLY1305 can trigger the crash; on OpenSSL ...
