OpenSSL -- multiple vulnerabilities

The OpenSSL project reports: Constructed ASN.1 types with a recursive definition could exceed the stack CVE-2018-0739 Constructed ASN.1 types with a recursive definition such as can be found in PKCS7 could eventually exceed the stack given malicious input with excessive recursion. This could resu...

MGASA-2017-0453 Updated openssl packages fix security vulnerabilities

OpenSSL 1.0.2 starting from version 1.0.2b introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the...

FreeBSD : FreeBSD -- OpenSSL multiple vulnerabilities (9f7a0f39-ddc0-11e7-b5af-a4badb2f4699)

Invoking SSLread/SSLwrite while in an error state causes data to be passed without being decrypted/encrypted directly from the SSL/TLS record layer. In order to exploit this issue an application bug would have to be present that resulted in a call to SSLread/SSLwrite being issued after having...

CVE-2017-3738

CVE-2017-3738 is an overflow bug in the AVX2 Montgomery multiplication used for 1024-bit moduli in OpenSSL. The issue affects x86_64 builds with AVX2 (not ADX) and can, in very unlikely cases, enable private-key recovery on affected architectures. OpenSSL 1.0.2n fixes the flaw; OpenSSL 1.1.0 is n...
