This could result in a Denial Of Service attack. There + are no such structures used within SSL/TLS that come from untrusted sources + so this is considered safe. + + This issue was reported to OpenSSL on 4th January 2018 by the OSS-fuzz + project. + (CVE-2018-0739) + [Matt Caswell] + + *) Incorrect CRYPTO_memcmp on HP-UX PA-RISC + + Because of an implementation bug the PA-RISC CRYPTO_memcmp function is + effectively reduced to only comparing the least significant bit of each + byte. This allows an attacker to forge messages that would be considered as + authenticated in an amount of tries lower than that guaranteed by the + security claims of the scheme. The module can only be compiled by the + HP-UX assembler, so that only HP-UX PA-RISC targets are affected. + + This issue was reported to OpenSSL on 2nd March 2018 by Peter Waltenberg + (IBM). + (CVE-2018-0733) + [Andy Polyakov] + + *) Add a build target 'build_all_generated', to build all generated files + and only that. This can be used to prepare everything that requires + things like perl for a system that lacks perl and then move everything + to that system and do the rest of the build there. + [Richard Levitte] + + *) Backport SSL_OP_NO_RENGOTIATION + + OpenSSL 1.0.2 and below had the ability to disable renegotiation using the + (undocumented) SSL3_FLAGS_NO_RENEGOTIATE_CIPHERS flag. Due to the opacity + changes this is no longer possible in 1.1.0. Therefore the new + SSL_OP_NO_RENEGOTIATION option from 1.1.1-dev has been backported to + 1.1.0 to provide equivalent functionality. + + Note that if an application built against 1.1.0h headers (or above) is run + using an older version of 1.1.0 (prior to 1.1.0h) then the option will be + accepted but nothing will happen, i.e. renegotiation will not be prevented. + [Matt Caswell] + *) Removed the OS390-Unix config target. It relied on a script that doesn't exist. [Rich Salz] @@ -5,7 +5,7 @@ This file gives a brief overview of the major changes between each OpenSSL release.
